Fox found fewer than 5 million total viewers to sing and dance with last night, per preliminary Nielsen numbers for “The Rocky Horror Picture Show.”

The broadcaster was able to move into the runner-up position in the key 18-49 demographic, but still settled for fourth place among total viewers. The special’s 4.9 million total viewers was far less than “Grease: Live’s” 12.2 million and even “The Passion’s” 6.6 million. To be fair, “Rocky Horror” was not live like the others were, so there was less incentive to tune in the same way.

CBS dominated the night with “Thursday Night Football” — stiff competition for the musical reboot, no doubt.
