I know several people who only watched the Superbowl for the advertisments / halftime show. Regardless of how shitty it is, one of the big cultural touchstones is also the advertisements they played on tv when someone was growing up. A lot of people use ads as another way to connect with a new person; meeting a other local to your area means you can mention a particularly overplayed ad from childhood and likely be able to find another person who saw it growing up too.
