Knock Knock Cancelled

Fox Cancels Seacrest's Knock Knock

Knock Knock Live has been Ding-Dong Ditched, pulled from Fox’s schedule after just two airings.

The Ryan Seacrest-hosted feel-good effort premiered last week to just 1.7 million viewers and a 0.6 demo rating, besting only CW reruns on that night.

In its second outing, it dipped to 1.6 mil and a 0.5 — despite the presence of the almighty Bieber.

In its place, a one-hour Last Man on Earth rerun will fill the Tuesdays-at 9 time slot on Aug. 4. From there on, a combo of Brooklyn Nine-Nine/Last Man repeats will occupy the hour.
