As one of the world’s leading publishers of books, DVDs and courses devoted to the subject of American Football, we couldn’t really be expected to let Sunday’s Super Bowl to pass without comment, so here goes.

As Seattle Seahawks, the defending champions, prepare to take on New England Patriots, the most dominant NFL team of the last 15 years, the match has become one of the most intriguing in the 49-year history of the competition.

It’s no surprise that these two teams will meet at the University of Phoenix Stadium in Glendale, Arizona as they both finished the 2014 regular season with the best record in their respective conferences.

The accomplishments of both teams have been largely overshadowed by the “Deflategate” controversy, which the NFL is still investigating.

However, the incident shouldn’t affect the game itself, which could turn out to be one of the more memorable in recent Super Bowl history given both clubs’ strong play in recent seasons.

Here are some of the more obscure facts about Sunday’s game that you may not know.

Could be most-watched TV show ever
Last year’s game was the most-watched TV show in U.S history with an average of 111.5 million viewers. It broke the previous records set in 2012 and 2010.

Seahawks make back-to-back trips
Seattle is the first team to play in consecutive Super Bowls since New England did it in 2005 and 2006. The Patriots were victorious in both games.

Tom Brady sets Super Bowl record
Brady will become the first quarterback to ever start in six Super Bowls. He had been tied with John Elway, who played in the game five times.

Most-experienced Super Bowl coaching head to head
Bill Belichick will coach his sixth Super Bowl, while Pete Carroll has reached the game for a second time, setting a record with eight combined appearances between head coaches. When the Patriots played the New York Giants in 2012, Belichick and Tom Coughlin combined for seven appearances.

Game returns out West
The contest hasn’t been played outside of the eastern or central time zone since 2008 when it was last held in Glendale. Super Bowl 50 in 2016, will be played in San Francisco’s Levi’s Stadium.

Expensive tickets
Tickets are being priced higher than ever before on the secondary market, with the average asking price reportedly surpassing $6,000.

Pricy commercials
The commercial breaks (and there are many of them) are almost as eagerly anticipated as the game itself, as giant corporations bid to outdo each other in producing the most talked ads.

The cost of a slot is quite staggering with the average price being around $4.5 million this year.

Whoever wins Super Bowl 2015, the event is already set to be the biggest ever – until next year that is.
