Red Bull purchased the team and used it as a vehicle to promote their product. Which they have also done with RB Salzburg, RB Leipzig, RB Brasil and RB Ghana (on the pitch).
There was talk last year that they were also looking to purchase a team in the English Champioship. RB Leeds United, perhaps.
Anyway, teams with corporate names is part of the game's history - Bayer Leverkusen for instance. Also see Army and Police teams (particularly in Russia and Communist Germany in the day).
As you were.
The difference, for me, is that they implement the brand in the North American style - the team is technically called the NEW YORK RED BULLS, and the team's branding is awash in Red Bull logos and colours. "RB New York" sounds far less chintzy.
