The Toronto Blue Jays were in back-to-back World Series in their championship seasons of and , as well as the 1991 ALCS . All of CBS 's postseason telecasts were simulcast on CTV ( which earned CBS approximately $ 7.5 million per year ) in Canada , and received very high ratings north of the border when the Jays were involved . Unfortunately , Canada does not factor in the Nielsen ratings so as a consequence , CBS earned the lowest ratings in over 20 years for a World Series ( not counting the earthquake interrupted 1989 World Series that was televised by ABC ) . In any other World Series , viewership would have likely been higher since two American teams would have been involved , to say nothing of spikes to off-the-chart ratings shares in the two competing cities ( especially in when CBS was fortunate to cover the riveting , ultra intense , seven-game battle between the Minnesota Twins and Atlanta Braves ) . Another reason behind the poor ratings likely had to do with the gradual attrition of the audience for almost all network programming
