what year did the cb radio come out
Citizens band radio The citizens band radio service originated in the United States as one of several personal radio services regulated by the Federal Communications Commission (FCC). These services began in 1945 to permit citizens a radio band for personal communication (e.g., radio-controlled model airplanes and family and business communications). In 1948, the original CB radios were designed for operation on the 460–470 MHz UHF band.[3] There were two classes of CB radio: "A" and "B". Class B radios had simpler technical requirements, and were limited to a smaller frequency range. Al Gross established the Citizens Radio Corporation during the late 1940s to manufacture Class B handhelds for the general public.[4]
Vehicle audio In 1964 Philips launched the Compact Cassette, and in 1965 Ford and Motorola jointly introduced the 8-track tape in-car tape player. In subsequent years cassettes supplanted the 8-track, and improved with longer play times, better tape quality, auto-reverse, and Dolby noise reduction. They were popular throughout the 1970s and '80s. While the CD had been on the market since 1982, it was in 1984 that Pioneer introduced the CDX-1, the world's first car CD player. It was known for its improved sound quality, instant track skipping and the formats increased durability over cassette tapes. Due to the ability that allowed drivers and passengers to change up to 10 CD's at a time, car CD changers started to gain popularity in the late 80s and continuing throughout the 90s.[11] Stock and aftermarket compact disc players began appearing in the late 1980s, competing with the cassette. The first car with an OEM CD player was the 1987 Lincoln Town Car, and the last new cars in the American market to be factory-equipped with a cassette deck in the dashboard was the 2010 Lexus SC430,[12] and the Ford Crown Victoria.[13]
