For CBS' coverage of the 1991 All-Star Game from Toronto, CBS started their broadcast at the top of the hour with the customary pregame coverage. And then, because American President George H.W. Bush and Canadian Prime Minister Brian Mulroney were throwing out the first ball, there was a slight delay from the 8:30 p.m. EDT start. The game eventually started about 15–20 minutes late. Presumably this, along with CBS' low ratings for baseball, and the costs of doing pregame coverage, led to them starting the prime time broadcasts at 8:30 for the final two years of the contract, with little or no pregame content.
