As the NBA joins sports leagues around the world in allowing sponsors' names on jerseys, the Golden State Warriors have inked a logo deal with Rakuten worth a reported $60 million (50 million euros) over three years. The deal with the reigning NBA champions is just one of the sports sponsorships pursued by Rakuten, the Japanese e-commerce giant whose logo now graces the FC Barcelona kit. Rakuten chief Hiroshi Mikitani told a press conference in Oakland, California, on Tuesday that he was "thrilled" to announce his partnership with the Warriors and the NBA.
