With the constant topic of tv shows getting stalled or abandoned on DVD after X number of seasons have been released, I wonder which show has the most seasons out? I know the Simpsons has 11 out so far, and South Park 12. Both of these are current shows high in popularity and likely to get many more releases (how long until season 20 of The Simpsons reaches DVD I wonder). Are there other long running shows past or present that have more seasons already released on DVD?

Friends has 10 seasons out.

the 11th season of Dallas comes out this month. Only 3 more to go.

I've come across other series that have about 11 seasons out:

Cheers-11 seasons out
Frasier-11 seasons out
ER-10 seasons out, season 11 scheduled for July
MASH-11 seasons out

So far the only show with 12 seasons out already I've found is South Park.

Happy Days has 11 seasons total, but only 4 have come out on DVD or disc.....:(

All 8 seasons of The Andy Griffith Show has been released.
