Most of the technologies we use today, especially the smartphone, have completely taken over what were considered pioneering devices just a few decades ago. But almost every gadget today has an early version that changed the way people live.

Advances in design and technology have removed original products from the market but not from history. 24/7 Wall St. compiled a list of inventions that revolutionized many industries but have been replaced by completely new products.

The thought of the smartphone being cutting-edge technology may make teenagers laugh, but there was a time when people didn’t have everything available at the touch of a button. Long-distance communication was unheard of, and listening to music on the go was a novel concept.

Many other products would not exist today without their predecessors. Before there were tiny thumb drives that store gigabytes of data, there was the floppy disk with a storage capacity of just over two pictures. And long before the phone and fax machines, there was the telegraph.

To compile this list of pioneering inventions that hardly anyone uses anymore, 24/7 Wall St. reviewed company websites, reference materials, and media sources. We considered products that were invented mostly over the last 150 years and that have significantly changed the way people perform a task or communicate.
