The New York Red Bulls were established in 1994 as one of the first MLS teams to be created by the league. The ownership group is Red Bull, the creators of the popular energy drink. Distinguished players for the Red Bulls include Bradley Wright-Phillips, Tyler Adams and Aaron Long.
The New York Red Bulls do not play in New York City. Their stadium and team operations are based in Harrison, NJ and yet have never been called the "New Jersey" Red Bulls. Why is this? MLS when first created wanted in the New York market, but New York City wasn't available.
What the Red Bulls are doing is not unusual in the American sports ecosystem. Both the Giants and Jets play in East Rutherford, NJ but are "New York," american football teams. Both of these teams used to play in New York City, and thus claim New York. The Red Bulls, originally the Metrostars, played in Giants stadium in New Jersey when founded. This is why the "New York," naming while never being located in New York City was so readily accepted by the media.
With the addition of New York City Football Club to MLS, the Red Bulls's location has continued to become talking point. With a club located in New York City (NYCFC play in Yankee Stadium in the Bronx, NY) fans are wondering if Red Bulls would ever change the name. At this time, it does not appear if Red Bull, the company who owns the club, has any intention of making a change.
