Local businesses will be able to videotape their own “shop local” announcements during the Brookline Chamber of Commerce’s annual holiday party, which takes place from 5:30 to 8 p.m. Wednesday in the Brookline Access Television  studios at 46 Tappan St. In addition to holiday festivities, partygoers can tour the studios and tape their own public service announcements. The videos will be edited by BATV staff for chamber members to post on their business websites. Admission to the holiday party is $10 for chamber members and $20 for guests.
