The company was founded by Vebjorn Tandberg as Tandbergs Radiofabrikk (Tandberg's radio factory) in Oslo in 1933. The company's first radio was named "Tommeliten", and used only earphones. This was followed by the "Corona" with a loudspeaker. In 1934 the first "Huldra" radio was launched, followed in 1936 by the "Sølvsuper". During the early years, radios, loudspeakers and microphones were the main output from the factory. The Sølvsuper and the Huldra radios became the foundation for Tandberg's success.
In the early 1950s, Tandberg opened a branch plant in Kjelsas (in Oslo) to produce reel-to-reel tape recorders. Their first model was the TB 1, introduced to the market in 1952. Over the next decade, Tandberg quickly incorporated a number of leading-edge concepts; the TB 2 Hi Fi of 1956 had three tape transport speeds, allowing improved high-frequency response. The TB 3 Stereo from 1957 was Tandberg's first stereo system. In the 1960s Tandberg introduced the cross-field recording technique in the TB-6X model, allowing their recorders to handle higher frequencies than competing models. Tandberg licensed the concept to Akai, who used it widely in the 1970s and 80s in their Akai and Roberts recorders.
