Terms of the deal have not been disclosed. Serino Coyne is Broadway's biggest marketing and ad agency, and recently created and trumpeted the current "Tuesdays at 7" campaign, a program in which Broadway curtain times Jan. 7-March 24 are earlier than usual on Tuesdays (the poorest-selling night of the week) to entice families , older folks and office workers.

Serino Coyne and other business partners, including the Broadway ad agency Spotco, Playbill and the League of American Theatres and Producers, created the annual "A Season of Savings" initiative, offering a Playbill-like coupon booklet with discount offers to plays, musicals, Times Square-area restaurants and hotels.

At the time of the 2002 "Season of Savings" push, Nancy Coyne, president of Serino Coyne, said in a statement, "A Season of Savings makes it easy and affordable for metro area residents to enjoy a night out at the theatre. The colorful Playbill provides special offers to a wide selection of great Broadway and Off-Broadway shows. Based on our first success we believe that consumers will hold on to this Playbill so they can take advantage of more than one offer throughout the fall."

Variety reported the firm handles marketing for more than half the productions currently on Broadway.
