Rumors are already out that how Google advertisements are displayed is going to change. They will not be incorporating logos and other graphics into their advertisements which is something Google has not looked fondly on in the past.
One format being discussed is a box, which may include a photograph and a logo, that would appear on the main search results pages toward the bottom of the advertisements in the right-hand column. Traditional banner ads may appear on Google Image Search and the Froogle shopping site, which already include many photographs, an executive involved said. No advertising is contemplated for the Google home page.
