This year, a 30-second Super Bowl ad will cost companies $5.6 million – that's a whopping $186,666 per second.

Despite last year's game drawing in the lowest viewership in recent years at an estimated 98.2 million people, ad prices show no sign of dropping any time soon.

Prices have increased almost every year from a modest $37,500 in 1967. By 1994, the average cost of a Super Bowl ad had exceeded $1 million.

By 2017, the cost had hit $5 million, and according to Ad Age, $4.9 billion was spent on advertising for the Super Bowl between the years 1967 and 2017.

Since 2017, the average cost of a Super Bowl ad has continued to skyrocket. In 2018, the cost of a 30-second Super Bowl commercial was $5.2 million. In 2019, the average cost of a 30-second ad raised to $5.25 million.
