I'll withhold my opinion until I'm done reading and reflecting upon the study (on page 9 of 26...), but seems like posters here have bias of their own.
So far, the primary conclusion eBay draws is that display should get much more spend. eBay's display business is tiny while Google's is huge, so I don't think it's right to accuse eBay of ulterior motives.
More to come, but I'll say this - so far the study is reading like a solid refutation of paid search for the subset of companies that have moderate to strong brands.
