The World: New York - Advertising auction framework attracts criticism

Plans by a group of key US advertisers and eBay to launch an auction system for buying and selling national TV ads has run into trouble.

The Cabletelevision Advertising Bureau said its members, who include most of the country's cable networks, would not participate because of the system's shortcomings.

Sean Cunningham, the CAB president, said the system, which is backed by Toyota, Microsoft and Home Depot, had several problems, and pointed out that media agencies were divided about its feasibility.

John Muszynski, the Starcom chief executive, has claimed such auctions "commoditise" the buying and selling process and were a "waste of time".
