Last month Northstar announced the acquisition of the Original Home Based Travel Agent Show and Conference from Real Trade Shows.
Nielsen Business Media is divesting its trade publishing properties and late last year sold several magazines, including Billboard and The Hollywood Reporter, to private equity-backed e5Global Media.
A Nielsen Co. spokesperson declined to comment. Northstar CEO Tom Kemp could not be reached for comment by press time. However, Kemp told BtoB's Media Business last month that he was mulling further acquisitions. "What we want to do is take advantage of a weak M&A market if we can to try to find appropriate acquisitions at attractive prices," he said.
