Home Depot has become the second buyer to use eBay's Media Marketplace to purchase commercial placement, reports MediaPost.

Ad time was purchased on TV One, a newly emerging channel targeting an African-American audience. Because of its freshness in the market, TV One decided to offer its ad time up for sale, perhaps in hopes of drawing the attention of major ad distributors.
There was also bid interest from an ad agency, but that firm was not identified. TV One opted not to follow through on that lead because the agency was looking for deeply-discounted prices.

With two sales under the belt of eBay's ad platform, observers are looking at the process and awaiting a tipping-point, or discernible improvements or efficiencies that will make the model as fluid as online stock exchange platforms or bid-based marketplaces. Much of the negotiations and discussions still happen via email exchanges and phone calls.

Still, any news is good news for the start-up ad network, which has suffered from a lack of buy-in on the part of some buyers groups.
