Google celebrated its 15th birthday today. Though the company was incorporated a few weeks earlier, the company celebrates its birthday on September 27. It announced on its birthday that it is updating its search algorithm as part of an update it has named "Hummingbird". Three years ago it had an update it called Caffeine. Amit Singhal, a senior vice-president for Google estimates that the redesign will affect how Google analyzes about 90% of the search requests it receives. Singhal said that Hummingbird is primarily aimed at giving Google's search engine a better grasp at understanding concepts instead of mere words. The increasing use of Google's voice-recognition technology for spoken search requests through smartphones was a factor in the development of changes for Hummingbird.
Google's ad revenue related to web content is expected to approach $60 billion U.S. dollars this year.
