Classic TV diginet Antenna TV is making some schedule changes for spring, including the primetime return of Johnny Carson.

There are no additions to the lineup but the 5PM-7AM single episode experiment is going away. As of March 30, all half-hour sitcoms will once again be running back-to-back episodes.

The other major change: “Binge TV for Free” Themed Weekend Marathons. Marathons will run from 12 Noon to 12 Midnight Saturdays and Sundays, kicking off with Murphy Brown and Newsradio. The marathons are scheduled to air from March 28 through Sunday May 10.
