There are How Many Episodes of 'NCIS'?

Alert on Fox at 8:00pm ET. Two-hour first season finale.

America’s Got Talent on NBC at 8:00pm ET. First season finale.

The Neighborhood on CBS at 8:00pm ET.

NCIS on CBS at 9:00pm ET. 450th episode. This has been on the air longer than Grey’s Anatomy and just four years shy of Law & Order: SVU. I don’t hear the same general bafflement with it still being on TV, but that could be because most of the people making those jokes about Grey’s or SVU don’t even realize this is still running or how long it’s been on. It will be coming back for a twenty-first season.

Quantum Leap on NBC at 10:00pm ET.
