The Super Bowl is by far the highest advertisement cost $/second of any event each year. Companies spend insane amounts of money producing and running these ads, often new products are announced, etc.
It is stupid, but it’s not unusual for Americans to particularly care about ads on this one day per year.
giving me idiocracy vibes
It just is what it is. IMO it’s much less stupid than watching brain numbing sitcoms like “Big Bang Theory” or “Modern Family” every day.
As Derek noted, it’s usually just an excuse to have a big party with family & friends.
