As numbers of attendees increase, half of the 19 teams comprising the US Major League Soccer (MLS) federation have built new stadiums in the last five years.

With an average of nearly 18,000 fans per game last year, the sport once relegated to the sidelines of US athletics is now outpacing the NBA in terms of attendance.

Now as Texas's Houston Dynamos build the nation's first stadium intended specifically for football, the MLS is hoping that changing demographics may lead the game to experience its first true surge in the US.
