NBA2K has had "ads" on its loading screens for a couple years now. It's technically a "show" that mostly advertises stuff you can buy ingame.
It's amusing in the PC version because I've always been able to tell that it waits for the ads since it loads the game faster off my hard drive than the ads download and play. I think BisMarkie said it was the same in the PS5/XSX versions with the new SSDs.
