Notes
The Twin 125s aired on 2/16.
TNN debuted its NASCAR coverage under its own banner. The American Sports Cavalcade was no more. Although the two principals of said show worked these races.
The bulk of the Atlanta spring race was run on Monday, 3/18 after rain limited Sunday's on-track activities. It went untelevised.
Yes, the Snake appeared on the first three TBS races. He owned a late model stock car team at the time, plus he was already gainfully employed by Turner Sports. I can't exactly define what his role was. He opened up the first Richmond race in the booth, and closed the second Richmond race in the booth, for instance. During the Coke 600, he only appeared during a pre-taped segment. He didn't appear at all during the fall Charlotte race.
Generally I like to list the pit reporters in italics, but it should be mentioned that Economaki didn't exactly work the pits during the CBS races. But he conducted interviews during the races from an elevated location alongside pit road, and when he wasn't opening up the broadcast as the host, I figured it would make some sense to just list him as if he was an on-the-ground pit reporter.
