After World War II, the trend in home audio entertainment shifted from stand-alone radios with built-in speakers to individual components, including an amplifier, turntable, speakers, and a tuner, which was the fancy new hi-fi term for a radio. One of the first FM tuners was the Leak Trough-Line, which was co-designed by BBC engineers in 1954 and released in the U.K. in 1955. This somewhat clumsy looking model was updated in 1960 as the Trough-Line II, which had a plastic Art Deco front. Other companies that are highly regarded for their tuners include Marantz (the Model 10 arrived in 1960, followed by the more advanced 10B), Yamaha (its CT-7000 represented the state of the art in 1973), and Sansui (the TU-9900 from 1974 is still a favorite of audiophiles).
