The suspension of nearly all sports leagues and competitions due to the pandemic has caused complications for broadcasters, as major events constitute a type of television programming that can frequently guarantee a large number of live viewers, and, in turn, advertising revenue.[156][157] The largest and most significant events also represent a major investment by broadcasters; in 2019, the total market for sports media rights in the United States was estimated at $22.42 billion, representing 44% of the international market.[158][156][159] CBS Sports and Turner Sports pay $785 million per-year to televise the NCAA Division I Men's Basketball Tournament – whose 2020 edition was scrapped only six days before it was scheduled to begin. In 2019, a 30-second commercial during the national championship game on CBS cost around $1.5 million, while CBS and Turner's contract to air the tournament accounts for nearly 72% of the NCAA's annual revenue.[156]
