It’s 80 years since televisions first went on sale in the shops. On July 3, 1928 you could have popped into your local electronics emporium and picked up a TV made by the Daven Corporation for the princely sum of $75.
The telly has come a long way since then, with high-definition LCD and plasma screens now taking the place of more traditional, boxy sets.
The first commercially available TV sets went on sale in the United States in 1928. Pictures were viewed on tiny screens, just a couple of inches in size.
The set pictured above was constructed from a plan published in the December 1928 and January 1929 issues of Popular Mechanics.
Daven Corporation, which made the first TVs to be sold in shops, also made all the components used to build this early set.
Early television sets were mechanical, but by the 1930s TVs had become entirely electronic.
During this decade, John Logie Baird made the first ever outside broadcast from the 1931 Epsom Derby.
The BBC also began broadcasting – televising the FA Cup Final for the first time in 1938. However, its operations ceased abruptly on the outbreak of war in 1939, with the British government fearful that broadcasts could be used by the enemy as homing signals.
The pictured television set, the Ecko TA-201, was made in 1939. It could receive just one channel and was for pictures only (sound could be heard by connecting it to a radio). It cost 22 guineas – or around £1000 in today’s prices.
By the 1940s, television had really started to take off in America – aided by the popularity of stars such as Milton Berle and Ed Sullivan.
In Britain, the BBC resumed broadcasting in 1946 following the end of World War II. At the same time it also introduced the licence fee – £2 at the time.
The pictured set, the Bush TV-12, went on sale in 1948 and was pre-tuned to receive one channel. Its successor, which followed two years later, could be tuned to any of five channels
The TV boom truly hit Britain in the 1950s. The coronation of Queen Elizabeth II attracted huge viewing figures, and was the first time a TV audience had exceeded a radio audience.
By the end of the decade, more than 10 million TV licences had been issued in the UK, and popular programmes such as Grandstand, Blue Peter and Panorama had begun.
In the States, colour TV was introduced and innovations such as videotaping and remote controls were demonstrated.

Television technology developed rapidly during the 60s. By the end of the decade, colour broadcasting had begun in the UK, while portable TVs went on sale for those looking for a second set.
In America, TVs could now be found in 90% of homes. When Neil Armstrong took his first steps on the Moon, a global audience of 600 million people was watching.
The picture shows a stylish set manufactured by the West German KUBA Corporation. Called the Komet, the set stood 5′ 7″ tall, with the upper section rotating so the viewer could swing the 23″ black and white television and speaker system in the desired direction.
The system cost around $1250 at the time – around £6000 in today’s money.
By the start of the 1970s, 16 million TV licences had been issued in the UK.
TV sets were improved with the introduction of electronic channel tuning, and the videotape wars began with the introduction of Sony’s Betamax system (1975) and JVC’s VHS technology (1978).

By the 1980s, TV accessories such as video recorders and remote controls had become commonplace.
Screen sizes were also becoming bigger, although the proportion remained 4:3 rather than the now-familiar widescreen 16:9.
In the UK, Channel 4 began broadcasting, as did Sky television towards the end of the decade.

By the start of the decade, 900 million TV sets were in homes around the world.
Major advances in telly technology included the introduction of Nicam stereo sound and the broadcast of programmes in widescreen.
Towards the end of the 90s, early adopters began buying the new, flat plasma screens that were appearing at the top end of the market. Also, the new DVD video format was launched in the UK.
And so to today. Nowadays, bigger is better, with screen sizes of 37″, 42″ and even larger becoming increasingly common. The screen pictured above is a whopping 60″ in size.
High-definition is the most recent technological advance, with digital broadcasts and Blu-ray players making it possible to watch programmes in pin-sharp detail.
