What band beat out the Beatles when the two groups auditioned for a contract at the London studios of Decca Records?
Brian Poole & the Tremeloes, in 1962. Decca’s decision reportedly was based on location—the Tremeloes were from the London area, making them more accessible than the Liverpool-based Beatles.
THE SCIENCE OF TV
How remote controls work
When viewers push a button on their remote, it releases a specific digital pattern (or code) of infrared waves, which the television interprets as an instruction. They’re called “infrared” waves because they have a slightly lower frequency than red light, the lowest frequency of visible light. But they have a higher frequency than radio waves, so they can’t penetrate walls. Infrared remote controls also use cheap and readily available transistor technology, and since they don’t have mechanical components, they can be small and thin. In 1980, electrical engineer Paul Hrivnak formed Viewstar to manufacture infrared remotes. They cost about $100, but in five years, Viewstar had sold a million of them. By 1990, infrared technology dominated the remote market. The device now comes with radios, computers, CD players, MP3 players, as well as TV sets, and is considered a household necessity.
