You don’t see a lot of traditional advertising from Google. Their philosophy is to build great products and develop amazing technology and let it sell (and support) itself. Their marketing strategy has relied mostly on word of mouth – and its worked well. It just may not be enough for a company their size.

They’ve hired an agency for a campaign in Japan called “100 Things You Can Do With Google.” However, unlike many top brands Google ads aren’t running on prime time.
