David Levin, CEO of the London-based B2B media conglomerate United Business Media, is a featured speaker at our “Future of Business Media” conference in NYC next week. The company is the owner of CMP, PR Newswire and other B2B brands. I spoke to him last week on changes at CMP, the future of online and events business, downturn if it comes, the M&A market, and other issues. Lots more here.
