4TAB commenced 1 January 1992. The official opening was conducted on air on 23 January 1992.
Prior to the licence being bought by the TAB, the station was known as 4IP. It commenced in 1935. Between 1965 and 1977, 4IP had a most successful hit music format in Brisbane, and was aligned with its Melbourne and Sydney cousins 3XY and 2SM. In the 1980s, FM radio started making inroads into 4IP's popularity it changed its callsign to 4IO and adopted a slogan of Radio 10, then STEREO 10 and later "Light and Easy 1008".

The majority of RadioTAB's programming is a continuous broadcast of thoroughbred, harness and greyhound racing. This occurs daily from 11:30am. While overnight from 2am, a shared programme is taken from Sky Racing.
Following the merger of Tatts Group, which operated RadioTAB for its jurisdictions (its wagering services then styled UBET), with fellow wagering and gaming operator Tabcorp, RadioTAB is now a sister station to Sydney-based Sky Sports Radio. Both stations have retained their separate identities as of 2021.
