@Del They'll need to show videos like Normani's, Nicki Minaj's and Cardi B's below for at least 6 hours a day (I wonder if @Pioneer1 and @Mel Hopkins think Cardi B's video's visuals and language is appropriate for kids too? I nicknamed it "nipples galore").
A number of "reality" TV show where provocatively dressed Black women, with Blond weaves (that all the Black women here love), throw drinks in each others faces and engage in affairs and other dysfunctional behavior.
They'll need some Tyler Perry dramas like the ones that saved Oprah's network. Another Empire or Power program would be helpful.
Of course well need sports but I doubt they have money to get professional sports out the box. Maybe they can broadcast some HBCU games the half time shows with dancers and music might would draw viewers.
They shouldn't waste money on journalist to cover relevant news of the day. They can simlly troll "black Twitter" for the freshest viral content and have some trendy millennials discuss it. They could take Tavis Smiley or Roland Martin out of mothballs to provide some semblance of serious journalism without actually doing it.
Maybe live stream TD Jakes and some other megachurches each Sunday, followed by a weekly motivational message from the Obamas.
Have some infomercials for HTC, CBD, Vape, Opiod, liquor, hair care, and weight loss products.
Finally they'll need comedy and pleny of it!
These things will help guarantee broad appeal and financial success of the new network.
