The 2013-14 broadcast TV season got off to a high-octane start Monday night, with a new series staking an early claim to being the season’s first breakout hit. Fox won the night on the strength of that new series, the drama "Sleepy Hollow," based on Nielsen numbers for the key 18-49 demo.

TVbytheNumbers.com reports that "Hollow" notched a hefty 3.5 average rating in viewers 18-49, in final numbers for the night. Trying to keep pace were the season premiere of ABC’s "Dancing with the Stars," which delivered a 3.1 to finish second, while CBS’s season finale of the summer sensation "Under the Dome" came through with a 2.8 to place third.

"Dancing" delivered a huge number in total viewers, averaging 16.04 million to lead all broadcast programs. "Under the Dome" was second with 12.1 milion, and "Sleepy Hollow" rounded up 10.1 million.

Fox opened its Monday prime time with the season premiere of "Bones," settling for a 2.3 in the 18-49 demo to set the stage for the big "Sleepy Hollow" premiere.

In the "not-so-notable summer finales" category, NBC’s "Siberia" closer mustered a 0.6 average in 18-49, while CW’s "Breaking Pointe" finale settled for a puny 0.2.

Preliminary numbers for prime time overall showed a competitive two-way race, with Fox taking the win for the night with a 2.8 average in adults 18-49, followed closely by ABC with a 2.6. Trailing were CBS (1.9 average), NBC (1.2), Univision (1.2) and CW (0.2).
