How many new sitcoms (black and white) have been cancelled in the last 5 years. Your more likely to get a reboot/spinoff of an old sitcom than a new one cause they are stale. And by stale I mean 90% of sitcoms have the exact same situation. Family with kids or group of friends dealing with issues (love, dating, school, racism, technology, seniors, babysitting, pregnancy, etc, etc, etc.). You're lying to yourself if you think sitcoms aren't stale. They all cover the same issues and stories that were already done in the "golden age" of sitcoms and long before that. You really think there's enough fresh material to have 5-10 black sitcoms on air doing different things? That's just not realistic and is a waste of time and money to make a pilot that no one cares to watch cause there's already 10 shows like it on air.
how many shows in general get canceled? that's nothing new....family ("this is us" is one of the top shows right now) & friends dealing with issues also drive tv dramas and all sorts of movies...like wtf are you talking about? if that's the case everything is stale
and comedic movies and romcoms are nothing but long form sitcoms, yet that genre still pumps out dozens of movies each year, with some breakthrough hits. people have not just lost their will to laugh at stupid shyt, no matter how many times it's been done. it's always sunny is still going strong, veep is still hot - having won plenty of awards, curb is back, master of none has been a hit, the league was a hit, goldbergs has been a hit, blackish has been a hit, big bang theory is or was pulling in somewhere near the highest network ratings....stop. yes, the drama is back, it's going strong and bringing movie level writing, acting, and effects to tv, but the sitcom isn't dead.
and yes, there is enough material to have 5-10 black sitcoms - a girlfriends type show, is different from some family set in the inner city, which is different than some bourgie black couple, which would differ from a show set in a black workplace, etc. furthermore a show geared toward people 50 and up (think the jeffersons) will explore different themes than one targeting 18-34 yr olds (atlanta), which will be different from something targeting kids and young adults (like sister sister or moesha). look at two of the breakthrough black shows right now (insecure and atlanta), they deal with many of the same things: young black friends, relationships and navigating careers with some social subtext - two shows with that much overlap are doing perfectly fine, and they have left plenty of room for other black sitcoms to explore.
edit: i just saw you started a south park season 21 thread....then have the nerve to talk about stale
