The first five days of “March Madness” college basketball have seen rising ratings and slightly lower national TV advertising exposure and spending versus a year ago. There have been 5,140 airings of TV ads on CBS, TNT, TBA and truTV, totaling $409.3 million in national TV revenue spent, according to iSpot.tv. A year ago, it was $428.4 million for 5,347 airings.
Although CBS’s primetime viewership was down Thursday night, the network’s ratings don’t reflect the total number of people who tuned in to watch the first game of the annual NCAA Men’s Basketball Tournament. The game also aired on truTV, TNT and TBS.
