SING OFF FINALE: RATINGS DROP

The fourth season of NBC’s The Sing Off signed off Monday night with its lowest ratings ever for a finale of the quickee talent-competition series. It averaged 5.19 million viewers, but was nevertheless the second most-watched TV show of the evening, behind a rerun of CBS’s Mike & Molly, which attracted 5.67 million viewers. Ratings for all the broadcast networks were down Monday largely because of last-minute shopping activity before the Christmas holiday and Monday Night Football on ESPN, which saw the San Francisco 49ers take on the Atlanta Falcons in a closely fought contest that ended with a 49ers’ win.
