Webpronews is reporting on the latest Google ad experiment. In 2005 Google said :-
"There will be no banner ads on the Google homepage or web search results pages. There will not be crazy, flashy, graphical doodads flying and popping up all over the Google site. Ever."
& guess what the experiment is? yep, banner ads.
Carry on like this & Google can not be described as a search engine, it is a brand engine.
