Its mission is to unite, strengthen and promote the theatre community in the San Francisco Bay Area.
The region has more theatre companies per capita than almost any other metropolitan area in the U.S. and is home to the third largest community of Equity (union) actors, following New York City and Chicago.
TIX Bay Area was a walk-up box office, located on Union Square, San Francisco, California.
In September 1987, under Theatre Bay Area's executive director and Callboard managing editor Deborah Allen, the publication grew to a 7-inch-by-11-inch format.
The name Callboard was changed to Theatre Bay Area Magazine in January 2004 in an attempt to more accurately reflect its content.
