The Boombox, the Discman, and the iPod arrived over the following decades, replacing the transistor radio and, further, eroding broadcast radio’s status as the most important way to reach the masses with music and ideas.

The transistor radio began to decline in popularity in the late 1970s as the cassette and the Walkman took over. By the early 1960s almost every family had a transistor radio. Texas Instruments devised processes for mass-producing transistors for their radios, and in the process, proved that transistors and their subsequent products could be affordable, more portable and more effective than vacuum tubes. Furthermore, through the late 1970s, many residents of Pustunich engaged in petty. The transistors, though, were what really made the project possible. The speaker, capacitors, and other components were created just for this project.

Together, the two companies created a radio called the Regency TR-1, which was announced on Oct. Texas Instruments used Bell Labs' breakthroughs in germanium transistors to develop a small, pocket-sized transistor radio, with the help of a small Indiana company named IDEA.
Device manufacturers had been using vacuum tubes profitably for many years, so they were understandably leery about switching to transistors.īut Pat Haggerty, vice president at a company called Texas Instruments, was convinced that transistors were going to revolutionize the electronics industry. In 1954, transistors were proven but novel electronic components.
Convincing manufacturers that this basic concept would work on mass-produced products, however, wasn't such a simple task.
