Your complete home entertainment system: a Dynatron combined radio and television - it looks like it might also do as a sideboard - on show at Olympia in 1949

Televisions did not remain monstrously large for long, however, as is shown by this 1958 image of modern life in the new town of Harlow, Essex. They would have had ITV from London for three years by this point - although we're not expert enough to know what channel they have on

A Bush television from 1967 - still black-and-white, but able to handle higher resolution 625-line UHF transmissions, as well as the 405-line ones standard in Britain since 1936. BBC2 launched in 1964 as a UHF-only service, starting to add colour three years later; 405-line transmissions finally ceased in 1985

The next big thing? A 60-inch Sharp LCD panel for 3D televisions, unveiled in Tokyo this April. It uses a four-colour display - with yellow as well as the usual red, green and blue - to help restore the brightness lost by watching your TV through polarising glasses

Perhaps not the next thing, but certainly big - Panasonic's Toshihiro Sakamoto presents a 150-inch, or 6ft by 11ft, plasma screen at CES in Las Vegas, 2008
