CBS, TBS, TNT and Tru TV's March Madness coverage was the highest-rated first Thursday since 1991, Turner said Friday, citing Nielsen numbers.
The networks combined for an overnight household rating/share of 5.7/13, up 24 percent from a 4.6/11 for CBS Sports’ 2010 coverage of the NCAA Division I Men's Basketball Championship.
The 5.7/13 was the best first-Thursday rating in metered markets since 1991, when the tournament expanded to four telecast windows throughout the day.
