Introduction
Nielsen Television Audience Measurement Australia (Nielsen TAM) was originally established in 1999 as ATR Australia, later becoming AGB Nielsen Media Research, part of the global AGB Group. Awarded a seven-year contract to conduct Television Audience Measurement (TAM) in the five major Australian metropolitan markets from 1 January 2001, Nielsen TAM has since been awarded the contract to conduct and market TAM data for regional markets as of January 2003, and 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.
In April 2007 OzTAM reappointed Nielsen TV Audience Measurement Australia as the supplier of TAM services for the Australian metropolitan markets. The seven year agreement commenced on 1 January 2008.
At the start of the 2010 ratings year Nielsen TAM commenced measuring Time Shift Viewing for both the OzTAM and Regional TAM services. The increasing use of PVR's for recording, pausing and rewinding live TV was a major driver of this service enhancement.
Today, Nielsen TAM produces five audience databases twice a day, 365 days per year on behalf of both OzTAM and Regional TAM.
Nielsen globally measures more than 40% of the world's viewing behaviour - hundreds of channels, thousands of programs, millions of viewers in multiple countries across five continents. Nielsen continues to invest in technology, methodology and panel recruitment to ensure we remain the unquestioned leader in the field.
