I saw a lot of points on here that I agreed with and a few that I didn't, and I guess I will list my points and hope that people understand what I am saying.
1) BLACK TV SHOWS = BAD QUALITY: I know a lot of folks assume that an all-black cast automatically equals a bad show in terms of writing quality, but there were a lot of shows with large black casts that people ignored that were pretty decent. It happens with shows with white casts too, but the reasons might be varied as to why a white series might not succeed (bad timeslot, changing timeslot, bad acting, or usually something not related to the audience not giving the show a chance because of the racial composition of the cast).
Over the years, I have watched funny black sitcoms or quality dramas disappear from the TV screen and watched horrible shows (like those Tyler Perry sit-coms) stay on the air forever.
Here are a few quality black shows that got cancelled fast (in no particular order):
BUILT TO LAST (1997 season): This show starred comedian Royale Watkins (this was the black guy who was on the final season of the MTV dating show SINGLED OUT). It was an African-American middle class family living in Washington D.C. IIRC, and it was heartwarming and funny. Big family style comedy like JUST THE TEN OF US. Didn't last. I thought it was very, very smart and funny.
UNDER ONE ROOF (1995 season): This family drama was nominated for several Emmy Awards and it starred James Earl Jones, Joe Morton, and Essence Atkins (the shorter sister from the sit-com HALF & HALF). It was about a retired police officer living in Seattle sharing his home with his family. Another quality show, brilliant, but unheralded by the audience. Quality acting. Also cancelled fast.
LINC'S (1998-1999): This show was about a black bar owner in D.C. and his patrons. Starred Tim Reid (Venus Flytrap from WKRP in Cincinatti) and Pam Grier and was notable for its heavy right-wing/Republican views despite a predominantly black cast. Showed that not all blacks are left-wing liberal Democrats (something ignored by the media). Very, very, very smart show, lasted for a season and a half. Adult writing, nothing for kids on the show.
704 HAUSER (1994): This show starred John Amos (James Evans from GOOD TIMES) who played a retiree who moved into the old Archie Bunker house from ALL IN THE FAMILY. Also notable because the father in the show was a hardcore 60s black radical and his son had married a white woman and was a right-wing Republican. Was funny, but also didn't shy away from controversy.
Ugh... I gotta go to work... I will finish this later!
