Oh really, none of them were huh?
The Hughleys was on for 4 years total. Maybe except for Tracy Morgan, everything I listed was on for like 4-5 years. Shows these days dont last 1 season most of the time.
You're one of the worst posters on this board. And that's saying alot.
That's because your definition of success in this instance is not the a major network's definition
Most of the shows you mentioned lasted longer because they weren't on major networks...stations like UPN or the CW are willing to let low rated shows stay a float for awhile to find an audience...on a major network they don't allow shows to stick around and wait for an audience
go back and look at the ratings for the shows you mentioned.
My Wife And My Kids is the only show you named that the network was happy with...it went five years...although it's ratings fell off a cliff the last season which is why it didn't get renewed
Everybody Hates Chris (a show I love by the way) never drew good ratings...it's first year was it's best and it was still like the 120th rated show on TV and barely drew 4 million viewers...after that it never even saw three million viewers...and by it's last season it dipped below two million viewers
The Hughleys...they had one good year...their first year they were getting over 12 million viewers...but by year two they lost four million viewers then got shipped over to UPN where it finished up it's last two years with basically no one watching
just because a show is on one of these smaller networks for awhile doesn't mean it's a "success" for the network...they need a certain amount of viewers to bring in ad revenue to pay for the production of the show
and the shows just want enough episodes to reach syndication to get that re-run money...just look at Fringe (another show I like)...that show is losing money...and the studio ponied up their own money to keep it on this last season to hit the number of episodes they need to reach syndication.
so yeah...the whole post is kind of off, because you define success different than a major network defines success.
