Radio years

Kapsch produced its first radio receiver in 1923. At the same time, a struggle for the first license to broadcast a radio program flared up. Kapsch became a founding member of RAVAG, the Radioverkehrsgesellschaft (radio transmission company), which won the tender in 1924. Regular broadcasts began in Vienna in October 1924. The growth of the industry was reflected by the expansion of manufacturing capacity: Kapsch began operating an additional factory in 1927.

Radio Catalog

around 1927, Title Page (Reproduction)

Radios were sold by many small retailers; specialized radio dealers were only beginning to appear. This made it even more important to publish attractive catalogs and to advertise the brand in magazines. In the 1920s, Kapsch advertised with the slogan: ‘Wer von Radio spricht, meint Kapsch’ (‘Anyone who talks about radio means Kapsch’).

Josip Sliškovič with an Early Television Set

1930

This television set was based on the system of the Nipkow disk, whose holes were arranged concentrically. By rotating the disk, images could be broken down into light-dark signals and transmitted wirelessly. Following the rapid spread of radios, the assumption in 1930 was that television would soon follow.
