Thursday night -- which generally draws more television viewers than any other night of the week -- saw a big drop in viewers versus the first Thursday night of the season last week. In particular, Fox's The X Factor saw its numbers drop 12 percent from last Thursday, while NBC's Whitney plummeted 24 percent and ABC's Charlie's Angels dropped 29 percent. CBS's The Big Bang Theory remained the top-rated show of the night, drawing 14.5 million viewers in the 8 00 p.m. hour. The X Factor managed to attract 11.9 million viewers in that hour. Meanwhile, during daytime, ABC's The Chew has been quickly losing viewers since its premiere on Monday. Between Monday and Wednesday it has dropped 14.3 percent of its audience and is now down 15 percent below the average of All My Children , the soap opera that it replaced.
