This thread is for long running scripted shows that are constantly being moved around. The 4 or more timeslots is for completely different slots, being moved back to the same slot it moved from doesn't count (example: Frasier had 4 regular timeslots but 2 of them were the same).

limit of 4 shows per post

Wings
Bones
3rd Rock from the Sun
Diagnosis Murder

Designing Women ran for 7 seasons and was moved several times. I'm not sure of the exact moves but I'm almost positive it was constantly being switched around.

MASH-that started on Sundays at 8 for its first season, then it was moved to Saturday at 8:30, then Tuesday at 9, Wednesday at 9, Friday at 8, then back to Tuesday at 9, then Monday at 9.

I Dream Of Jeannie--After becoming a surprise hit on Saturday in its freshman season, it bounced back and forth between Monday and Tuesday at the beginning of each of the next four seasons. Although it only ever aired at 7:30 on Tuesdays, on Mondays it aired at 8PM in its second season and 7:30 in its fourth, bringing the total to four slots.

Maude--After two seasons on Tuesday, it moved to Monday where it bounced back and forth between 9PM and 9:30 slots for the next three years, finally moving to Saturday nights midway through its last season.

Green Acres--Had a solid home at 9PM Wednesdays for three years, then it moved back to 9:30, then to Saturdays at 9, then finally Tuesdays at 8.

Mary Tyler Moore--although it spent its entire seven-season run on Saturday night, it was scheduled in all four half-hour slots between 8 and 10 at some point in its run.
