Do you Know ? Can Google be made April Fool?

Yes google also cause by the april fool. The first think was to make it appear its name as topeka only in USA search engines and else where the google logo remains the normal. SAN FRANCISCO - Internet giant Google turned its mega search engine on its ear Thursday by changing its name to "Topeka" in a huge cyberspace April Fool's joke.

Google said the move was inspired by a Kansas town which in March changed its name to that of the Internet giant as part of a US bidding process to be the test hub for the company's experimental super-fast broadband network.
"Early last month the mayor of Topeka, Kansas stunned the world by announcing that his city was changing its name to Google," Google chief executive Eric Schmidt said in the company blog.
"We've been wondering ever since how best to honor that moving gesture.
"Today we are pleased to announce that as of 1:00 am (central daylight time) April 1st, Google has officially changed our name to Topeka."
