Demonstrating yet again that there are viewers ready to gather around their TV sets on Saturday nights if they have something appealing to watch, CBS's coverage of the NCAA Men's Basketball Tournament attracted 15.92 million viewers on Saturday, nearly twice the number of viewers who tuned into the other broadcast networks -- combined. While no other TV show drew as many as 3 million viewers, NBC was particularly hard-hit. Its expensive-to-produced Smash, which was banished to Saturday night after failing to find an audience on Monday or Tuesday, attracted just 1.88 million viewers. The show is burning off its remaining episodes on Saturday night and is virtually certain to be canceled before the end of the season.
