And that's great but the original topic was the TV broadcasts of that era, not the sport in general. Those are what I can't get warm fuzzies over, mostly because there was so much less coverage. The booth crews can be debated but as far as the sheer amount of programming available, this does indeed strike me as the Golden Age.
I think the 90s and 2000s were the Golden Age for television. Between ESPN Speedworld, TNN Motorsports and Speedvision in the 90s, and SPEED in the early 2000s, you got NASCAR Winston Cup, Busch Grand National, Craftsman Truck Series, ASA, ARCA, Goody's Dash, Winston West, Busch North, Slim Jim All Pro, NHRA, IndyCar, Champ Kart, three different types of sports car, boat racing, bike racing, swamp buggy racing and so on. There was almost always something on, whether it was ESPN, TNN, Sunshine Network, The Family Channel, or so on. You also had shows like RPM 2Night which covered a wide array of motorsports and Inside Winston Cup.
The 2000s brought the blockbuster Fox/NBC deal which led to expanded television coverage of practice, qualifying, NASCAR TV on Speed Channel, daily NASCAR programming, more coverage of ARCA.
Things aren't that bad today though. We've got racing on FS1, NBCSN, MAVTV and CBS Sports Network quite frequently. And then the internet's opened up a whole new world of possibilities with dirt racing and pavement short track racing. Every NASCAR K&N and Modified race is being broadcast live for free on FansChoice. Every CARS Tour race is broadcast live. World of Outlaws and the Lucas Oil series are live online and often on television. Speed51 airs CRA, Southern Super Series and big events such as Winchester and the Snowball.
