The top mobile phone advertising platform was the iPhone, with 15% of the market, followed by RIM’s Blackberry Curve with 4.4% and Motorola’s Droid Razr with 4%. When combined with advertising served to tablets, Apple grabbed about 28% of impressions, followed by Samsung with 18%.

As a group, smartphones took 73% of all advertising in the first quarter, up from 62% in the same period a year ago. Tablets, however, took 20% of impressions, up from 15% last year, and now claim nearly 3x the ad impressions for feature phones.

The data comes from a survey by Millennial Media Inc. (NYSE: MM), a mobile ad network that competes with Apple’s iAds and Google’s AdMob.

Millennial also note that of the top 10 devices that display ads, 3 were tablets. A year ago only Apple’s iPad made the top 20. The two additions this year were Samsung’s Galaxy Tab and Amazon’s Kindle Fire.

As tablets attract more buyers, it’s reasonable to expect that their share of the ad market will grow. Recent research from Nielsen indicates that tablets get 24% of all Worldwide Web ad clicks, compared with just 11% for phones. Tablets are more like desktop and laptop computers and users may click on ads because of the more familiar size of the screen. The small screens on smartphones are not as easy to use to find things quickly — and that’s the appeal of smartphones and smartphone apps — to find exactly what a user wants with the least amount of fuss.

This is good news for Apple, of course, and not-so-good news for Google, which pays a hefty price in traffic acquisition costs to maintain its position as the default search engine on OEM smartphones, including iPhones. By one estimate Apple gets 50%-60% of the revenue from a Google search on iOS, whether from an iPhone or an iPad. Google probably does not have to part with quite as much revenue for devices from other makers, but a cut of about 40% would match Google’s reported traffic acquisition costs. Google needs to find a way to hold onto more of its search revenue because its mobile ad network simply can’t make up the lost cash flow.

Einhorn’s reasons for beating up on Amazon’s stock are not compelling. Wall St. does not need to look beyond the recent results of JCPenney (NYSE: JCP) and other mid-tier retailers, or even big-box retailer Walmart (NYSE: WMT). Online shoppers have found Amazon irresistible. It has run several competitors, particularly Barnes & Noble (NYSE: BKS), almost out of business.

A victory over competition is not necessarily an outright win. Amazon has to show consumer loyalty and profits to make a final convincing case. The well-regarded Foresee study of e-commerce user customer satisfaction had Amazon on top again. It was even ahead of Apple’s (NASDAQ: AAPL) e-commerce customer satisfaction, and was it far ahead of e-commerce satisfaction for all bricks-and-mortar retailers. The survey was based on a large sample of 21,000 respondents, too.

The other criticism of Amazon concerns its margins. Despite a 34% increase in Amazon’s revenue last quarter to $13.2 billion, net income fell 35% to a tiny $130 million. There are at least two ways to look at the net income figure. One is that Amazon cannot control its costs despite rapid sales growth. The other is that the company has elected to forgo higher margins for now because there is a cost to crush competition. The value of Amazon’s stock indicates a majority of investors believe that the second case is true.

The debate about Amazon’s future reemerges with each new earnings report and product introduction. Despite these questions, Amazon has overcome the rule that sales growth slows as companies get larger. Only a few other companies that have been public for a long time have also been able to demonstrate this. Apple is the first one that comes to mind.

Amazon, despite Einhorn’s protests, has shown almost nothing to shake the opinion that nearly every major decision made by its management has made has been right.

Samsung Electronics (OTC: SSNLF.PK) recently introduced a 4.8-inch screen on its Galaxy S III, half-an-inch larger than the 4.3-inch screen on the company’s existing Galaxy S II model. The new device is scheduled to launch in the US this summer.

The larger iPhone screens are being manufactured by several suppliers, including LG Display Co. Ltd. (NYSE: LPL), Sharp Corp. (OTC: SHCAY.PK), and Japan Display Inc.

Apple is reported to be considered making a smaller version of its iPad tablet as well. Like the iPhone, the tablet’s screen size has remained unchanged since the iPad’s introduction. Other tablets, including the Kindle Fire family from Amazon.com Inc. (NASDAQ: AMZN) and the Nook from Barnes & Noble Inc. (NYSE: BKS) have had success with smaller screens.

Apple and Samsung currently account for more than 50% of all smartphones sold, and Apple’s iPad really has no serious competition yet in the tablet market. The issue for Apple is whether or not it wants to get out in front of the mobile device market with a new product that raises the bar for everyone else. A “me-too” smartphone with a larger screen or a similar shrinking of the iPad screen is not the sort of change a leader makes. Especially when the evidence (i.e., sales) indicates that consumers can’t get enough of the products you already have.

Apple’s strength has always been to build a product that none of us knew we wanted because we don’t have the vision. Anybody can make screens bigger or smaller. Apple should be doing something else. Like building a cheaper phone that would appeal to the half of the world that can’t afford to buy the current iPhone.

A review of the biggest losers demonstrates how little consumers care about prior successes. Although these companies were the industry darlings once, today consumers may not even remember their names.

Companies such as Nintendo, Research In Motion, Sony and Nokia dominated their markets for a number of years and, in many cases, had few to no serious competitors. These companies often rose to the top because of major breakthrough products, such as the Nintendo Wii, RIM’s BlackBerry and Sony’s Walkman.

But the companies on this list have not managed to adequately follow up these successes with new products and now are losing ground to competitors. Sharp has lost money due to competition from companies like Samsung that have stronger brands and can undercut its prices on TV. Nokia, which continues to do well in the low-end cell phone market, is losing money because it has been unable to make a significant break into the growing smartphone market.

24/7 Wall St. has identified eight of the most popular tech brands that are losing money. To demonstrate these companies’ waning popularity, 24/7 reviewed financial data from their financial statements, as well as data from a number of major research firms.

These are the eight great tech brands losing money.

1. RIM

Research In Motion (NASDAQ: RIMM) was, for a time, a leader in the smartphone market. Its BlackBerry phones helped pioneer the industry. The company’s popularity has since waned and it has begun to lose money. In the fourth quarter of fiscal 2012, RIM had a net loss of $125 million, the result of goodwill charges and “an inventory provision taken primarily on certain BlackBerry7 products.” Revenue was down 24% compared to the year prior. According to Comscore, RIM’s share of the U.S. market for smartphone subscribers dropped from 16% last December to 12.3% in March. Meanwhile, the share of smartphones using Google’s (NASDAQ: GOOG) Android rose from 47.3% to 51% over the same period. The company’s BlackBerry 10 handsets, which are being released later this year, may be RIM’s last chance for relevance.

2. Sharp

Sharp reported a record annual loss of $4.67 billion this past April. The company also announced that it expects to continue to lose money in the current fiscal year. Sharp’s losses are primarily due to falling prices and declining sales of its LCD televisions. The Japanese company has been struggling to compete with South Korean manufacturers. In addition, the company spent $1.5 billion in restructuring costs. In March, Sharp sold a 46% stake in its largest plant to Taiwanese rival Hon Hai to soften losses at its television business.

3. EA

Electronic Arts (NASDAQ: EA) reported a net loss of $205 million for the fiscal third quarter ending December 31, 2011, despite generating $1.06 billion in net revenue over the same period. Two of the company’s major titles — FIFA 12 and Battlefield 3 — have each sold more than 10 million copies, a particularly large quantity for games. Madden 12 has sold nearly 5 million. Many experts believe that the company’s launch of The Sims Social — meant as a competitor to Zynga (NASDAQ: ZNGA) products — has not done well. This was viewed as a gamble on EA’s part, as the company has spent hundreds of millions of dollars trying to break into the social games space. It is not the first time for EA to be in the red. The company had a net loss of $322 million in the same quarter the year before.

4. Sony

Sony (NYSE: SNE) was a world leader in a variety of electronic products only a few years ago. As recently as November 2011, the company cut its sales forecast for TVs, cameras and DVD players. The company’s financial situation has only worsened since then. In April 2012, Sony decreased its earnings outlook for the fourth time in less than a year, warning of a potential $6.4 billion net loss in the last fiscal year. The Wall Street Journal said the loss would be “the biggest-ever in the electronics conglomerate’s 65-year history.” Sony has been dealing with ongoing losses in its television segment. In its consumer electronics arm, the company has been struggling to deal with competition from companies like Apple (NASDAQ: AAPL) and Samsung. Sony also has lost its standing in the game console market, which it once owned with the PS2, and in the portable music device market, which it owned with the Walkman.

5. Nintendo

Nintendo was the number one video game console manufacturer in the world thanks to its Wii. In order to better compete, Microsoft (NASDAQ: MSFT) and Sony slashed prices on their Xbox 360 and PS3 products. Nintendo, as a result, was forced to drop the prices of both its Wii and portable player DS. In April 2012, the company posted a total loss of $461.2 million for the 2011 fiscal year. All three companies also face the growing competition posed by smartphone-based gaming.

6. Nokia

Nokia (NYSE: NOK) has long been the world’s largest handset manufacturer, but it lost that position to Samsung in the first quarter of the year. Its past success was due, in large part, to the company’s low-end cell phone models, which are particularly popular in developing countries. When it came to smartphones, however, Nokia has not kept up. The market continues to be dominated by Samsung and Apple. Nokia’s inability to break into the more profitable smartphone arena has been apparent in the company’s profit and loss statements. In April 2012, the company announced a quarterly net loss of $1.2 billion, blaming “greater than expected competitive challenges.” In an attempt to turn itself around, Nokia has set a joint venture with Microsoft to distribute Windows mobile on its smartphones in exchange for financial and marketing support.

7. Barnes & Noble

Barnes & Noble (NYSE: BKS) has invested increasing amounts in its Nook e-book reader. But intense competition from other tablet and e-reader companies, including Apple and Amazon.com (NASDAQ: AMZN), has kept the company in the red. For the 39 weeks that ended January 28, 2012, Barnes & Noble lost more than $11 million. The company blamed the increasing losses on continued investments “in its rapidly growing Nook business, including advertising costs and personnel.” To help it with the Nook development costs, Barnes & Noble has also formed an alliance with Microsoft. The software company has made an investment in the book company’s e-book and e-reader businesses in exchange for the creation of Nook models that run the Windows OS.

8. Acer

Acer’s business plan used to rely on the netbook, the cheap, portable and underpowered laptop. In the past two years, however, netbook sales have been disrupted by the surging tablet market, as well as the growing popularity of smartphones. Dropping the price did little to encourage demand. The company reported a massive annual loss of $212 million in 2011. Now the company is focusing on the Utlrabook, Intel’s (NASDAQ: INTC) laptop and effectively the next generation of netbook. It appears the company has not learned its lesson. According to The Verge, Acer Global President Jianren Weng predicts that PC Ultrabooks will drop to $499 in 2013 to compete with Apple’s iPad. Unfortunately, that is several hundred dollars less than the company needs to make money.

Arch Coal Inc. (NYSE: ACI) saw a gain of 18.7% in short interest as of for the two weeks ended April 30th. More than 6.6 million shares were added to short interest and 20% of the company’s float is now short. The coal miner’s poor earnings and forecast are to blame.

Short interest in Exco Resources Inc. (NYSE: XCO) rose nearly 12% to more than 33.5 million shares, or 19.3% of the company’s float. The oil & gas driller missed revenue expectations, although it did post a profit. Revenue is more important now however.

Among the largest overall short positions, SandRidge Energy Co. (NYSE: SD) got short interest on 49.5 million shares, nearly 12% of its float and up 6.7% from the previous reporting period. Shares are down more than -33% in the past 12 months, and the small spikes don’t affect short sellers here. The long-term outlook for natural gas continues to call for weak pricing.

E&P company Forest Oil Co. (NYSE: FST) was another recipient of more short interest in late April. Short sellers added about 3 million shares, a 24.7% increase and enough to put nearly 13% of the company’s float short.

Even Exxon Mobil Corp. (NYSE: XOM) didn’t escape. Short sellers added 7.7 million shares to their positions, a 31.8% change to 32 million shares, but still less than 1% of Exxon’s shorts.

The final energy company we’ll look at here is Duke Energy Corp. (NYSE: DUK), where 5.8 million additional shares were added to short positions, bringing total shorts to just over 79 million shares. That’s an addition of 8% and represents 5.9% of Duke’s float. It’s odd to see a utility on this list.

Advanced Micro Devices Inc. (NYSE: AMD)saw short interest in its share rise by 6.5% to more than 70 million shares or 11.9% of the company’s float. AMD continues to suffer from lower-than-expected earnings and revenues.

Short interest in Sanofi (NYSE: SNY) jumped 265% to more 13.4 million shares. While still only about 0.5% of the company’s float, but generic drug sales are hurting the company as is a weak economy in Europe. Neither condition is expected to improve soon either.

Short interest in Pfizer Inc. (NYSE: PFE) also rose sharply, buy 21.4% to reach a total of 63.6 million shares, about 0.8% of the company’s float. Like Sanofi, competition from generics hurts. The company also said it will reduce marketing expenditures on its Lipitor drug.

Nokia Corp. (NYSE: NOK) gets the honor for being the equity with the largest number of short shares, 195 million, which represents 5.2% of the company’s float. The good news is that short interest fell by more than 32 million shares, also the largest change.

More than 75% of Barnes & Noble Inc.’s (NYSE: BKS) float is short, about 19.8 million shares. Short interest in the company grew by just 700,000 shares since mid-April.

Short interest holds more than 42% of grocer SuperValue Inc.’s (NYSE: SVU) shares with a total of 88.5 million shares short, up slightly from two weeks ago.

Short interest in Pitney Bowes Inc. (NYSE: PBI) actually fell slightly , but the company’s total of 50.5 million shares short represents 25.3% of the float and 22 days to cover.

Short interest in for-profit educator DeVry Inc. (NYSE: DV) jumped 123.2% to 3.7 million shares or 6.3% of the company’s float. Another education company, Bridgepoint Education Inc. (NYSE: BPI) posts short interest of more than 9.7 million shares, or 56% of its float.

24/7 Wall St. screened out selective short interest data with the latest changes from the settlement date of April 30, 2012 versus the prior April 13, 2012 in shares of the following: Alcatel Lucent S.A. (NYSE: ALU); Banco Santander, S.A. (NYSE: STD); Bank of America Corporation (NYSE: BAC); Barnes & Noble, Inc. (NYSE: BKS); Dendreon Corporation (NASDAQ: DNDN); Diamond Foods, Inc. (NASDAQ: DMND); First Solar, Inc. (NASDAQ: FSLR); Green Mountain Coffee Roasters, Inc. (NASDAQ: GMCR); Groupon, Inc. (NASDAQ: GRPN); Human Genome Sciences, Inc. (NASDAQ: HGSI); LinkedIn Corporation (NYSE: LNKD); Netflix, Inc. (NASDAQ: NFLX); RadioShack Corporation (NYSE: RSH); Research in Motion Limited (NASDAQ: RIMM); and Sirius XM Radio Inc. (NASDAQ: SIRI).   Does this make for a “Short-Sell in May and go away!” theme?  The short interest changes are for the April 13 versus March 30 settlement dates, with selective color added if applicable:   Alcatel Lucent S.A. (NYSE: ALU) saw another rise in the short interest but this gain was massive by over 25% to 28.67 million shares in the short interest.  Based on its earnings botch, the short sellers made some real money here.

Banco Santander, S.A. (NYSE: STD) is not one of our usual short interest names but investors are back to betting against Spain and the PIIGS all over again now that austerity measures are being fought publicly.  The prior gain was a whopping 214% gain in the short interest to 55.7 million shares and the newest gain was only 2.5% to 57.1 million shares.

Bank of America (NYSE: BAC) is back to seeing a rise in the short interest after a prior drop.  Short sellers lifted the short interest by 9.9% to 142.3 million shares.

Barnes & Noble, Inc. (NYSE: BKS) saw a small increase ion its short interest, which you know helped to exacerbate that pop from the Microsoft deal while activist investors press on here.  The short interest rose another 3.7% to 19.768 million shares.

The FORESEE E-RETAIL SATISFACTION INDEX (SPRING TOP 100 EDITION 2012) is the result of approximately 21,000 responses from visitors to the top 100 retail sites. The data posts year-over-year comparisons of both industry average satisfaction and satisfaction with individual retailers.

The bottom ten sites in the survey, based on a total best score of 100 were:

Nutrisystem.com (NASDAQ: NTRI)  74

PCConnection.com 74

PCMall.com 754

Safeway.com (NYSE: SWY) 74

Abercrombie.com   73

Build.com 73

Gilt.com 71

Peapod.com 70

Ancestry.com (NASDAQ: ACOM) 69

efollett.com 69

The presence of Gilt at the bottom is somewhat of a surprise given that it caters to high end customers.

At the top of the list, are several companies which would be expected. The first among them is the world’s largest e-commerce company–Amazon (NASDAQ: AMZN). Fortunately for Barnes & Noble (NYSE: BKS) which is in a battle with Amazon in the e-reader business, its site scored well. The company recently took an investment from Microsoft (NASDAQ: MSFT) to expand its Nook e-reader division. Apple (NASDAQ: AAPL), which is generally well-regarded for customer service across its online and bricks and mortar retail operations, also did well. The one surprise on the list is Avon (NYSE: AVP), which has struggled with its image.

According to IDC data, worldwide tablet shipments totaled 17.4 million units in the first quarter, nearly -7% below the company’s projected total. The projection represented a sharp decrease in expected shipments following the fourth quarter of 2011 when 28.2 million tablets were shipped. The sequential drop in shipments came in a -38.4%.

Apple’s share of tablet shipments rose to 68% in the first quarter, from 54.7% in the fourth quarter of 2011. Units shipped totaled 11.8 million iPads, down from 15.4 million units in the prior quarter. IDC attributes Apples success to two decisions:

Apple’s move to position the iPad as an all-purpose tablet, instead of just a content consumption device, is resonating with consumers as well as educational and commercial buyers. And its decision to keep a lower-priced iPad 2 in the market after it launched the new iPad in March seems to be paying off as well.

Amazon’s share of global shipments fell from 16.8% in the fourth quarter to just more than 4% in the first quarter, falling behind Samsung Electronics into third place. Lenovo and B&N rounded out the top five.

IDC noted that it expects second quarter shipments to improve as new products enter the market, with a significant caveat to vendors:

[T]o compete in the media tablet market with Apple, [vendors] must offer their products at notably lower price points.

IDC expects a Google-Asus tablet to come into the market at a price point to challenge the Kindle Fire. And a tablet using the Windows Phone 8 platform from Microsoft Corp. (NASDAQ: MSFT) is due in the fourth quarter of this year.

The takeaway from this appears to be that Apple will continue to dominate while the other vendors fight for share among themselves. Apple’s decision to continue selling the iPad 2 puts an upper limit on lower-priced competitive tablets as well. There’s still a fair bit of room between the entry price of a Kindle Fire or a Nook and an iPad 2.

The trick for Google-Asus, Amazon, and the others will be to find the highest price point they can below the iPad 2 entry level price of $399 while still offering the same or more features. Then they have to be prepared to drop their price if/when Apple does. This is not a game for the faint of heart.

When the shares popped to above $24.00 this week based upon the Microsoft investment, Jana unloaded a portion of the stock it recently purchased.  A filing from the Securities and Exchange Commissions from Wednesday evening showed that on April 30, 2012 Jana Partners LLC sold 1,000,000 Barnes & Noble shares at a price of $24.42 per share.  The investment group is far from being out of the position because the same filing shows that it still owns (or owned) some 5,959,359 shares of Barnes & Noble common stock as of April 30.

It is of course possible that Jana unloaded more shares and that later filings will come, but the firm signaled that more good things will come for the company (see below).  On April 30 the stock traded more than 29.5 million shares and it hit a high print of $26.00 after opening at $25.79 with a close down at $20.75.  This was a true profit-taking opportunity for anyone who has bought the stock and held on in hope of a successful go-private transaction or in hopes that activist investors would win here.

Liberty Media Corporation (NASDAQ: LMCA) may be the real winner here with its stake and exposure but its shares rose less 1% on the news since its market cap is already over $10 billion.

What is interesting is that Jana’s Barry Rosenstein commented on CNBC with David Faber just on the same Monday that there is a long way to go with this stock but he would not comment on Jana’s trading strategy on this.  Rosenstein did talk a long-term game even though the newer filing shows that his firm may have been selling right into the commentary he was making.  He thinks that brick & mortar business is a value and when Jana bought it was getting the Nook business for free.  Rosenstein also noted that only 35% or so of the stock is in the free float.

It is not surprising at all that Jana would have sold some of the stake when it had a 90% to 100% or so in profits in such a short period of time.  Perhaps the only shocker should be that the activist group only unloaded about one-seventh of its position.

The news comes just a few days after Barnes & Noble Inc. (NYSE: BKS) announced a new joint venture with Microsoft Corp. (NASDAQ: MSFT) to put more effort behind B&N’s Nook e-reader. The Kindle devices and the Nook use customized versions of the Android operating system from Google Inc. (NASDAQ: GOOG).

Reuters reported this morning that it received an email from a Target spokesperson announcing the company’s decision, but declining to say whether Target was developing closer ties with Apple or did not want to sell a device that enriched a major competitor like Amazon. Target has said it would continue to sell the Nook e-reader.

Apple plans to open mini-Apple Stores at 25 Target locations during the year, at terms that are reported to be quite favorable to Target. Perhaps Apple did a little arm-twisting, or more likely, Target saw which side of the bread had the most butter. Pushing Amazon’s Kindle would cut into its more profitable deal with Apple, and help one of Target’s bitterest rivals in the bargain. The Nook remains, presumably with other low-selling products, to give the impression of variety and choice that Target claims to offer to customers.

Target’s shares are down about -0.9% at $57.49 in a 52-week range of $45.28-$58.95. Amazon’s shares are up 0.3% at $230.82 in a 52-week range of $166.97-$246.71. Apple’s shares are up 0.4% at $584.30 in a 52-week range of $310.50-$644.00.
