Radio manufacturer founded 1932 in London by Harry Roberts and Leslie Bidmead. The company was the first British manufacturer to produce a radio using an Integrated Circuit. In 1955, they received a Royal Warrant to the Queen, and later to the Queen Mother and the Prince of Wales in the 1980s. They produced televisions under the 'Dynatron' and 'Roberts Video' brand names, and briefly produced portable record players under the 'Mayflower' name in the 1950s. In the 2000s, they began to sell branded BBC World Service wide band radio sets (World Radio Receiver sets) and digital radios (DAB sets).

During the 1980s, the company had been struggling, but in 1989, one of their classic red radios appeared in a Martini TV advert. This revived interest in the 1950s radio, and following the sell-out of two limited runs of this radio, the company decided to have a full reissue of the design which they called the 'Revival' starting in 1993. By 2000, the radio had been released in new colours and designs and has become Britain's best selling portable radio.

The company was bought by the GlenDimplex Group in 1994 at which point the headquarters were moved to Mexborough in South Yorkshire where the company still resides today.
