The Informationsgemeinschaft zur Feststellung der Verbreitung von Werbeträgern (IVW) (Information Community for the Assessment of the Circulation of Media, comparable to the Audit Bureau of Circulation) certifies and audits the circulations of major publications, including newspapers and magazines within Germany.

Since the IVW was founded on November 4, 1949, the testing association has continuously expanded its control activities and adapted its individual test procedures to the new requirements of the advertising market.

It was founded by the publishers in cooperation with the Central Association of the German Advertising Industry (ZAW).

Today (as of 2006) the IVW collects and controls distribution data for almost the entire range of advertising media in Germany.
