The British government and the state-owned postal services found themselves under massive pressure from the wireless industry (including telegraphy) and early radio adopters to open up to the new medium. By the mid-1960s, the Radio Corporation of America (RCA) were using metal–oxide–semiconductor field-effect transistors (MOSFETs) in their consumer products, including FM radio, television and amplifiers. When radio was introduced in the early 1920s, many predicted it would kill the phonograph record industry. By the end of the decade, they were established commercial modes. Radio was a free medium for the public to hear music for which they would normally pay. The most common type of receiver before vacuum tubes was the crystal set, although some early radios used some type of amplification through electric current or battery.

Many individuals—inventors, engineers, developers and businessmen—constructed systems based on their own understanding of these and other phenomena, some predating Maxwell and Hertz's discoveries. Many contributed to wireless. The development of metal–oxide–semiconductor (MOS) large-scale integration (LSI) technology, information theory and cellular networking led to the development of affordable mobile communications.
