Cross Talk: Season 3, Episode 10

"How Transistors made Radio truly portable - 65 years ago". From December 5, 2019.  The hot-ticket item for Christmas-time shopping in 1954 was a new style of Radio.  Portable, compact, even small enough to fit in the palm of your hand.  The transistor radio sparks another revolution in radio listening, and in radio programming for the teenagers who flock to buy the new devices.  Makes Fair Dealing use of bits from tv commercials and promotions for radio companies in the 1950s including RCA, Remco and Sylvania.  Reference to SONY, Bell Labs, Texas Instruments, Smithsonian Institute.  For educational purposes. The photo here shows a SONY labeled at the Museum of Science in London in 2016 as being one of the first compact transistor radios; model number not clear. It's a hand-held model about the surface size of an iPhone 4, but about three times as thick.
