This is why soccer (European football) is so much better to watch. No commercials. The game plays until the time runs out.
Instead of a 1 hour game of football (American), it runs to well over twice that amount, not including the pre and post pontifications.
Here's the way pro football works. Flip the coin to decide who kicks off. Go to commercial. Come back from commercial and have kick off. Four seconds elapse then play is ended. Go to commercial.
Have first three plays of game. Go to commercial. Punt ball away or get second series. Rinse and repeat.
