Associated Press: CBS will finish the television season as the nation’s most popular TV network for the eighth consecutive year, and win among the youthful demographic sought by advertisers for only the third time since modern record-keeping began in the 1980s. CBS’s victory among all viewers was its 13th in the past 14 years, Nielsen said. Fox won in 2007-8, when a writer’s strike kept most fresh scripted series off the air while “American Idol” was at its peak.
