Yahoo! Apparently IS Testing PPCall
I received a call from a Bloomberg reporter tonight (cellphone reception in an elevator no less) who said that Yahoo! had acknowledged to him that the company was in fact doing a test of PPCall with Ingenio's product (kind of double hearsay).
We went through all the usual stuff about the value proposition of PPCall and the contrast with PPClick. Anyway, I told him that this would give the medium an additional boost of legitimacy and open it up to a wider base of advertisers almost immediately (depending on whether/when Yahoo! adopts and rolls out).
This is getting way ahead of things and I wouldn't have commented again on this, except I think there's going to be a piece on it. He said he couldn't decide whether he was going to file the story. But I'm assuming he will.
