after 1953 further increased the popularity of television sets in the 1960s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media in the 1970s, such as VHS and later DVD, as well as for early home computers and videogame consoles. In the late 2000s flat panel television incorporating liquid-crystal displays largely replaced cathode ray tubes. Modern flat panel TVs are typically capable of high-definition display (720p, 1080p or 2160p) and can also play content from a USB device. Mechanical televisions were commercially sold from 1928 to 1934 in the United Kingdom, United States, and Soviet Union. The earliest commercially made televisions sold by Baird called Televisors in the UK in 1928 were radios with the addition of a television device consisting of a neon tube behind a mechanically spinning disk (patented by German engineer Paul Nipkow in 1884) with a spiral of apertures first mass-produced television set, selling about a thousand units. The first commercially made electronic televisions with cathode ray tubes were manufactured by Telefunken in Germany in 1934,1934–35 Telefunken , Television History: The First 75 Years. followed by other makers in France (1936), Britain (1936), and the United States (1938).America's First Electronic Television Set , Television History: The First 75 Years. The cheapest model with a 12-inch (30 cm) screen was $445 (). An estimated 19,000 electronic televisions were manufactured in Britain, and about 1,600 in Germany, before World War II. About 7,000–8,000 electronic sets were made in the U.S. before the War Production Board halted manufacture in April 1942, production resuming in August 1945. Television usage in the western world skyrocketed after World War II with the lifting of the manufacturing freeze, war-related technological advances, the drop in television prices caused by mass production, increased leisure time, and additional disposable income. While only 0.5% of U.S. households had a television in 1946, 55.7% had one in 1954, and 90% by 1962. In Britain, there were 15,000 television households in 1947, 1.4 million in 1952, and 15.1 million by 1968. By the late 1960s and early 1970s, color television had come into wide use. In Britain, BBC1, BBC2 and ITV were regularly broadcasting in color by 1969. By the late 2000s, CRT display technology was largely supplanted worldwide by flat-panel displays such as LCD. Flat-panel television, especially LCD, has become the dominant form
