Now in its fifth year, the UK-based Chester Group's New York Audio Show opens to the public this Friday, November 4, at 1pm in the Park Lane Hotel overlooking Central Park. (Friday hours are until 7pm.) The three-day show, a smaller version of what has come before, promises 30 exhibit rooms, half of which are "oversized," two ballroom-sized exhibits, and two more ballrooms filled with exhibits and vendors selling merchandise. All-in-all, the event, whose one-day visitor pass costs $30 ($26 in advance, with significant savings for multi-day passes) promises almost 110 brands.

Does marketing work? You betcha!
