The Totalisator Agency Board, universally shortened to TAB or T.A.B., is the name given to monopoly totalisator organisations in Australia and New Zealand. They were originally government owned, but in Australia most have been privatised. In Victoria, for instance, the Victorian Totalisator Agency Board began operating in March 1961 as a state enterprise, and was privatised in 1994.
Most Australian TABs have been progressively privatised, beginning with Victoria in 1994.
The TABs have extensive radio networks in Australia, except in Victoria and Tasmania where other parties own equivalent networks. All these networks share the National Racing Service, a continuous broadcast of thoroughbred, harness and greyhound racing. This makes up the bulk of these networks' content. Collectively, these networks own more radio licences than any other group in Australia - however, their terrestrial coverage is less than the ABC as they generally have tiny wattages. The heir of the NSW TAB also owns a national racing subscription TV service.
In New Zealand, the TAB owns TAB Trackside a former near-national free-to-air and national subscription TV service. Most New Zealanders could sit at their analogue TV with a standard aerial and watch racing. This channel is now only on Sky TV
The New Zealand TAB was replaced by the New Zealand Racing Board in 2003, however the physical premises have retained the TAB branding.
Radio TAB is also used to live sports coverage (including horse racing) in parts of Australia.
