The nets also use it to trot out some show that they want to draw a big audience to. If it's not a new show, it's always one of their bulwarks that they want to highlight. I remember a 1 hour "Friends" a few years ago with Jean-Claude van Damme after one of them, but usually, I've switched to either the History Channel, ESPN, or Fox News once the game is over.
Yup. Which is another reason why they should consider moving the game to Saturday night. People would be willing to stay up and watch those shows they want to push if they didn't have to get up early the next day.
