The company revealed the update at a party in Menlo Park on Thursday afternoon. BBC UK was there:

Google stressed that a new algorithm is important as users expect more natural and conversational interactions with a search engine – for example, using their voice to speak requests into mobile phones, smart watches and other wearable technology. Hummingbird is focused more on ranking information based on a more intelligent understanding of search requests, unlike its predecessor, Caffeine, which was targeted at better indexing of websites.

Google has also marked the occasion by creating a Google Doodle of the Google logo which turns into a video game piñata. You can hit it to knock candy out and earn points. Follow this link to work on your high score.
