What did ABC do in 1971 that changed tv? They broadcast Nss

NASCAR was usually tape-recorded, edited, and shown on such shows as ABC’s Wide World Of Sports.

 It wasn’t that there wasn’t a demand for racing, it was just that it wasn’t well known outside of the South.

In 1971 ABC televised the Greenville 200 race in South Carolina, Jim McKay and Chris Economaki were in the booth, while Ken Squier was in the pits talking with drivers as the race progressed.
