( EW.com ) -- Bazinga : CBS has overthrown Fox to win the 2012-13 broadcast season among the coveted adults 18-49 demographic . With only two nights left in the season , CBS claimed victory Tuesday given its insurmountable lead . The win snaps Fox 's unprecedented eight-year winning streak . CBS gets cocky : 'We are the center of the universe ' Among total viewers , CBS has led the broadcast field for years , ranking No . 1 during 10 of the past 11 seasons . But this is the first time CBS has won in the 18-49 demo in 21 years . CBS would even win the season if you excluded the network 's high-flying Super Bowl coverage . The network claims nine of the top 15 scripted primetime programs , including `` Big Bang Theory , '' `` NCIS '' and `` Person of Interest . '' During a press breakfast for reporters last week , CBS Corp. CEO Les Moonves relished the current standings . Yet CBS only deserves partial credit for its ranking . The network maintained roughly the same ratings as last year â€ ” which is certainly no easy task in an era of increasing DVR use , streaming and competition from cable networks . But it was Fox declining 22 percent due to softening `` American Idol '' popularity and other factors that gave CBS the trophy . Fox hopes to surge back next season with its new schedule , including the promising J.J. Abrams-produced action-drama `` Almost Human , '' and the use of short-order limited series , including a rebooted `` 24 . '' The `` Idol '' judges panel will be firmed up over the next couple months , and last night Fox announced an experienced new judges panel for `` The X Factor . '' Fox unveils fall schedule . The rest : NBC slipped slightly this season . But if you were to remove the Super Bowl from its average last year , NBC would have actually been up thanks to `` The Voice '' boosting its fall ( and despite a rather spectacular midseason ratings crash ) . ABC also fell , and this fall rolls out a whooping eight new shows . See the original story on EW.com .
