Upon the commencement of its coverage for the 2009 season, the BBC introduced complementary features such as the "red button" in-car camera angles, multiple soundtracks (broadcast commentary, CBBC commentary for children, or ambient sound only) and a rolling highlights package. Different combinations of these features were available across the various digital platforms in the UK and the BBC F1 web site) prior to, during, and after the race weekend. The BBC also broadcast a post-race programme called "F1 Forum" on the digital terrestrial platforms' "red button" interactive services.
