I think CBS has exclusive rights to live coverage. At 3pm eastern time, the CBS network starts live coverage. Prior to that time, live coverage is broadcast by CBS through its streaming service, Paramount+.
What is shown on the Golf channel is just replay and "analysis. "
Yes, but you have to go back to Freeper Wuli's initial question about why the Golf Channel wasn't showing the early live holes at all, even before the CBS national coverage began.
I said it was because of exclusive broadcast rights, except on days where CBS doesn't broadcast (non-subscription), that is, on Thursday and Friday.
