Nielsen Television Audience Measurement Australia (Nielsen TAM), an affiliate of Nielsen, was originally established in 1999 as ATR Australia, later becoming AGB Nielsen Media Research, part of the global AGB Group. Originally awarded a seven-year contract to produce Television Audience Measurement (TAM) in the five major Australian metropolitan markets from 1 January 2001, Nielsen TAM has since been awarded multiple contracts to continue to produce metropolitan and regional market TAM data, as well as continuing to report Subscription Television as of August 2003. The company was renamed Nielsen Television Audience Measurement in 2010 following the full acquisition of AGB by Nielsen, the largest provider of TAM services in the world.
