Super Bowl Commercials are one of the highlights of the Super Bowl, and the 30 second ad spots purchased are the most expensive advertising of the year. For Super Bowl XLV in 2010, the cost of each commercial was estimated at $2.8 - $3.0 million, with many companies buying multiple ad spots. General Motors is an example of this, and while they did not advertise during Super Bowl XLIV or Super bowl XLVII, they have purchased 5 spots for Super Bowl XLV. http://www.reuters.com/article/idUSTRE70D6QL20110114
Because of the cost and the competition, where many other commercials will also be aired and viewership is at its highest, Super Bowl ads are some of the most extravagant a company will produce. With costs nearing $100,000 USD per second of air time, a company can not afford to produce a sub par ad.
This competition leads to some truly great commercials, with no shortage of critics to review and critique each commercial. Dozens of "best of" lists featuring the top commercials can be found online for every Super Bowl, however, there is no authoritative source on the topic.
