The City of San Francisco had trouble finding a new naming sponsor due in part to the downturn in the economy, but also because the stadium's tenure as 3Com Park was tenuous at best. Many local fans were annoyed with the change and continued referring to the park by its original name, and many continue to do so to this day, regardless of the official name. Freeway signs in the vicinity were recently changed to read "Monster Park" as part of an overall signage upgrade to national standards on California highways.
