You're not the target demographic. If you were, the NBA would air one commercial and not waste their time marketing the event (since that's all you'd need to tune in). The target for any huge global event is anyone who otherwise wouldn't tune in. All-Star Weekend isn't for the hardcore junkie. Wrestlemania isn't for the neckbeard wrestling stan. You think the Superbowl is for the average fat white tailgater in flyover country who is gonna take time off work to watch the combine? No on all counts.
Now rap has a severe lack of accessible music compared to the 90s but y'all won't talk about that. The league would have Flo Rida on speed dial before they ever check for Future's availability or whoever else. Why? Because you're not the audience they're trying to attract. You're gonna watch anyway. It's been like this forever, only in the 90s, it was Coolio. It was Kris Kross. It was Naughty By Nature mixed in with some blatant pop and rock acts.
