That would be unacceptable to American TV networks, which demand steady streams of programming, week after week, to sell to their advertisers, who don't want to stop reaching a lucrative audience for a month or more in the middle of every season.
The real objection by the TV and cable nets is the fact that "normal" TV spots can only be inserted before and after the game and at half-time. It does not fit the model used for all other sports play by play.
In most of the rest of the world, advertisers buy the tagging of specific events in the game. Goals might include a sponsor name tacked on, just like the naming of stadium properties. Corner kicks, penalties, etc., can each be sponsored. But the tags are just brand mentions, not the spots sold on American TV in other sports.
