RaceCam

Although a vehicle-mounted 16mm motion picture camera was used as early as 1973, the technology was first developed in the late 1970s by the Seven Network in Australia, who introduced it for the 1979 Hardie-Ferodo 1000 endurance race at Mount Panorama in Bathurst, New South Wales with Sydney-based driver Peter Williamson able to give commentary from his Toyota Celica.

[2] American audiences were first introduced to RaceCam at NASCAR's 1981 Daytona 500 on CBS network with Terry Labonte's Buick Regal, and later at the 1983 Indianapolis 500, when ABC acquired the rights to use a streamlined version of the technology for their coverage of the race.

While Racecam units had become common place in NASCAR, unlike in Australian touring car racing the drivers generally refused to be wired to talk to the television commentators while driving, saying that it was too distracting.

Johnson, who had been using Racecam since 1982, also created a first for American NASCAR viewers when he was able to talk to the ESPN commentators during the 1989 Banquet Frozen Foods 300 at Sears Point Raceway.
