From "Naming rights could turn Dodger diamond into gold" at the LA Times:
Dodger Stadium will still be called Dodger Stadium in the years ahead, but much of the rest of the place is now available to be renamed -- for a price -- by corporate sponsors willing to add their brands to familiar features of Chavez Ravine. [...]
The Dodgers said Monday that they had formed a partnership with the William Morris Agency of Beverly Hills to identify opportunities to rename parts of the stadium and its planned $500-million addition. The expansion is intended to transform the ballpark into a year-round destination for dining, shopping and recreation -- and could also serve up numerous branding opportunities. [...]
As for the branding, William Morris has promised that the company names will be tasteful: Don't look for the Dodgers' exclusive Stadium Club to be renamed for a racy "gentlemen's club."
Hey, why not? Spearmint Rhino Dugout Club, anybody?
