ARS then announced on August 15, 1994 that it would purchase the programming and call letters of WEEI from Back Bay Broadcasting, effective August 29. As part of this transfer, WHDH's call letters were changed to WEEI and its format was changed from talk radio to sports radio, with on- and off-air personnel also being reassigned; 590 AM's call letters were concurrently changed to WBNW. WBNW simulcast the "new" WEEI for a week before Back Bay Broadcasting launched a business news format. The ownership transfer also saw WVEI break from its simulcast of WEEI to become a separate sports radio station for Worcester, WWTM; WWTM was acquired by ARS in 1996 and gradually returned to a simulcast of WEEI, returning to the WVEI call sign in 2000.
