We pretty much saw this one coming, but 90210 killed it in the ratings last night, and beat Gossip Girl, which aired on the CW just one night prior, by a landslide.
5 million people tuned in to watch the new series, whose ratings were 34% higher than GG. The CW is no doubt relying on the new 90210 to carry them through the season, so it's just a matter of whether people will continue to tune in to future episodes.
A lot of people tuned in for the premiere for pure curiosity and it didn't seem to deliver. We want to know. Will 90210 stay in your tivo, or get deleted?
