In America lately Google shows on the search page a large, advertising campaign Southwest Airlines and Virgin America. It seems that the company took back a promise he made eight years ago when he said we would never see commercials banner on the search page.
"Currently the advertising is very limited. Appears only on USA for testing," said a spokesperson Google in Huffington Post.
2005, Google has promised publicly that banner ads distract and will never tarnish its homepage. It was a promise given by Marissa Mayer (today is Yahoo's CEO), then head of Google's search and user experience.
Mayer worked on Google for 13 years before becoming Yahoo's CEO 2012.
