The Origins: From Toronto to Britain
How Brandes Began
The Brandes name traces back to a Canadian company established in Toronto in 1908, long before it became associated with Britain. <cite index=”1-1″>Brandes became part of AT&T in 1922, and a British subsidiary, Brandes Ltd, was established in Slough in 1924 to manufacture headphones.</cite> This move into the UK market laid the groundwork for everything that followed.
The Move to Foots Cray
As demand grew, so did the company’s ambitions. <cite index=”1-1,2-1″>The company rapidly expanded, producing a range of loudspeakers, and in 1928 moved to a former silk mill at Foots Cray.</cite> This site would go on to become synonymous with the KB name for much of the twentieth century.
How the Kolster Brandes Name Was Born
The distinctive “Kolster Brandes” branding didn’t exist from day one — it was the product of a corporate merger. <cite index=”1-1″>The company was renamed Kolster-Brandes Ltd after its American parent merged with the Kolster Radio Corporation.</cite>
Interestingly, the “Kolster” half of the name has its own engineering pedigree. <cite index=”10-1″>Frederick A. Kolster was a Swiss-born United States electrical engineer and inventor who founded the Kolster Radio Corporation.</cite> His earlier work centered on radio direction-finding technology used by the U.S. military, giving the eventual KB brand a foundation rooted in serious engineering credibility rather than pure consumer marketing.
Kolster Brandes’ Golden Era: Radios That Defined a Generation
The Masterpiece Radio and a Clever Marketing Move
One of the most memorable chapters in the company’s history involves cigarettes, of all things. <cite index=”1-1,3-1″>In 1930, the company supplied 40,000 of its Masterpiece two-valve, bakelite cabinet radios to the Godfrey Phillips tobacco company, which gave them away to customers in exchange for cigarette coupons.</cite> This kind of promotional partnership helped put KB radios into thousands of British homes at once, long before modern marketing playbooks existed.
Record Players and Home Entertainment
Beyond radios, the brand diversified into a wider entertainment catalog. <cite index=”2-1″>Kolster-Brandes later expanded into mid-range electronics including radios, radiograms, televisions, tape recorders, amplifiers, and gramophones.</cite> Its record players carried playful names that fit the era’s optimistic, domestic charm.
- Playtime
- Gaytime
- Dancetime
- Tunetime
- Rhythm (valve-operated)
The Cunard Connection: KB at Sea
Kolster Brandes’ reputation wasn’t confined to the living room. Through its later corporate ownership, the company found itself supplying communications and entertainment technology to one of the most famous ocean liners in history. <cite index=”1-1″>K-B began a long association with Cunard after winning a contract to provide communications equipment for the RMS Queen Mary.</cite> This maritime relationship extended to other Cunard vessels and became a point of brand pride for decades.
Television Innovation: The “Queen” Set
As British households transitioned from radio to television in the mid-twentieth century, Kolster Brandes moved with the times. <cite index=”2-1″>The company produced the “Queen” tabletop television set, one of the first affordable mass-produced television models, which used 20 valves and operated at 12 kV.</cite> For many families, a KB television was their first-ever window into broadcast entertainment.
Corporate Restructuring and the ITT Years
Absorption Into Standard Telephones and Cables
Ownership shifted again as the electronics industry consolidated. <cite index=”1-1″>In 1938, Kolster-Brandes became part of ITT’s British subsidiary, Standard Telephones and Cables (STC).</cite> The Foots Cray facility continued operating, now sharing space with related manufacturing operations under the same corporate umbrella.
Acquiring Rival Brand Names
Rather than compete against smaller manufacturers, the company absorbed them. <cite index=”3-1″>From 1960 onward, KB acquired the brand names Ace, RGD, Argosy, and Regentone, and continued manufacturing television receivers under the RGD brand into the 1960s.</cite>
The Slow Fade of the KB Name
Corporate identity kept shifting through the following decade. <cite index=”1-1″>In 1968, the Kolster-Brandes logo name changed to ITT KB, and between 1973 and 1974 the “KB” was dropped from the logo entirely.</cite> By the mid-1970s, the once-distinctive Kolster Brandes branding had effectively disappeared from the marketplace, folded into the broader ITT corporate identity.
