TS started in 1937 as a section within Institutet för marknadsundersökningar (IMU, the institute for market research) and became an independent company in 1943. It used to be jointly owned by the advertising bureau association (Annonsbyråföreningen) and the Swedish newspaper publishers' association (Tidningsutgivarna, TU). In 1994 it was sold to Scribona, an office electronics redistributor, which was a recent spinn-off from the Esselte group. Scribona then acquired Sifo, merged TS into this, sold it to the British WPP Group, where it became SIFO Research International. The main offices for SIFO and TS remain in central Stockholm, at Vasagatan 11. More information...
