In 1991, it cost CBS $4.8 million per game in venue productions alone to televise the National League Championship Series, not including studio backup operations or the satellite time needed to transmit the game to New York City for broadcast on their network frequencies. The American League Championship Series (between the Minnesota Twins and Toronto Blue Jays) was another problem because of the tariffs and labor laws they had to endure going into Canada. CBS averaged $1.9 to $2.4 million per regular season game. In return, it was typical for the production cost to double come playoff time. Ultimately, CBS reported a loss of around $169 million in the third quarter of 1991. A drop of in advertiser interest caused revenue from the sale of ads during CBS' baseball telecasts to plummet. All the while, CBS was still contractually obligated to pay Major League Baseball around $260 million a year through 1993.
