Attending live sporting events at an arena or stadium have long been part of tradition for many sports fans. It was also a great way to bond with friends and family to have a memorable experience together.  As years have passed by, less and less sports fans are interested in going to the stadium or an arena because they don’t want to deal with the hassle of high ticket prices as well as parking issues. The advancement of technology has made it easier for the sports fan to enjoy the game from the comfort of their own homes. Be it that they want to eat as much food drink as many beers as they want without going broke or wanting to keep up with their fantasy teams, and it's easy to see why fans choose to stay home.

The stadium owners and management have finally started to notice and now are upgrading or building stadiums to be the most high tech so sports fans have a better experience than they previously had. Sports and technology have collided and major communications and technology companies such as AT&T and IBM have partnered with the stadium to take the fan experience to another level and make it worth it to leave the couch.

With so many stadiums and arenas in the world the upgrades or building of new high tech stadiums will take time. But there are already some stadiums and arenas who have upgraded their technology and have become a major hit among the local and visiting sports fans.
