Boston’s Wang Center for the Performing Arts and the Commonwealth Shakespeare Company, which presents free summer productions, are merging their business operations together in an effort to streamline fundraising and marketing efforts. Each company will maintain its own distinct identity, but the agreement “formalizes and underscores the Wang’s sponsorship of CSC during the past two summer seasons. As CSC’s major underwriter, the Wang has contributed $200,000 in cash and thousands of dollars in ‘in-kind services,’ according to Maler.”
