Here we are, knee-deep in the 21st century, and CBS is still broadcasting “The Price is Right” (7 p.m., CBS) in primetime. During sweeps, no less. Bob Barker plays host, as he has since 1492. This is not the 21st century I had anticipated.

• Speaking of sweeps events, viewers can say goodbye to “Third Watch” (8 p.m., NBC). The cop/firemen/EMS drama goes out with a bang when angry gang members besiege the precinct house.

But before their fate is known, or sealed, as it were, viewers can catch a glance of former cast members Michael Beach, Eddie Cibrian and Kim Raver (currently playing Audrey on “24”). Aidan Quinn also guest stars, just in time for the riotous send-off.

In all honesty, I never understood the appeal of this paramedic soap opera. And I half suspected that NBC only kept it around so as not to upset its creator, John Wells, who happens to be the influential executive producer of “ER.” If you want to see a silver lining in the demise of “Third Watch,” perhaps this means that NBC will keep “American Dreams” around, also so as not to upset Wells, who also produces “Dreams.”

Tonight’s other highlights
