Tidningsstatistik AB (TS) is the company which measures newspaper circulation in Sweden.
TS started in 1937 as a section within Institutet för marknadsundersökningar (IMU, the institute for market research) and became an independent company in 1943.
In 1994 it was sold to Scribona, an office electronics redistributor, which was a recent spinn-off from the Esselte group.
TS is a member of the International Federation of Audit Bureaux of Circulations (IFABC).
Swedish daily newspapers monitored by TS have a total circulation of 3.72 million copies (2008).
