Online ad net Traffic Marketplace has acquired Livemarkets, a company that lets individuals strike up chat sessions with marketers within banner ads. Terms were not disclosed. The basic proposition behind Livemarkets, which was founded last year, is that consumers will click on an ad to chat with a customer service rep about the product featured in a banner. In one example on the company’s site, a consumer might click on a banner ad for a car to ask about a test drive. The “click-to-chat” function can work within any ad unit, Livemarkets says. As for Los Angeles-based Traffic Marketplace, the company bills itself as a “business-to-audience” ad net. It claims 30 billion ad impressions every month, delivering more than 20 million leads through its targeted display ads. Release
