AdBrite is keeping the network's current customers, and, yes, moving them to BlackLabelAds. Which means, as of December 1, AdBrite will officially be in the porn business. AdBrite serves 678 million impressions on its regular network and 267 million impressions on AVNads.com, which means porn ads make up roughly 28 percent of AdBrite's business. That may decrease, of course, if AVN is successful at luring away customers. (AdBrite founder Philip Kaplan has not yet responded to a request for comment, but I'll update the item when he does.)

From the tone of AVN's press release about the split, it seems like the squabbling pair has someone else to blame for their troubles: 365 Main, the troubled datacenter in San Francisco whose backup power system failed during a July power outage. AdBrite's ad servers were among those brought down. AVN goes on at length about its plans to host its network in multiple datacenters, with 24/7 monitoring. One wonders: If 365 Main's failures led, ultimately, to the demise of this relationship, would AdBrite and AVN have a claim for lost revenues?

Rumors reaching Valleywag from adult-industry sources indicate that Lehman Brothers was weighing a large investment in AdBrite — as much as 10 percent of the company — but decided to pass. That's a heavy blow for both AdBrite and its lead VC investor, Sequoia Capital, which frequently partners with Lehman. The reason for Lehman's cold feet? Apparently, AdBrite's involvement in the porn business was larger than bankers there had been led to believe — a fact that may have been uncovered during AdBrite's recent audit.
