Google’s realtime search, which used the Twitter stream to supply to-the-second relevant information in Google searches, has been shut down. Twitter and Google’s deal expired on July 2nd, so Google no longer has instant search access to the public stream. The deal originated in October of 2009, and there is no news yet whether the companies will renegotiate for an extension.
Realtime also used information from Yahoo Answers, Myspace and Facebook Page updates, Quora and Gowalla. These services are still associated with the project, and Google Realtime Search is expected to run again soon. According to Mashable, Google also plans to include public Google+ information in the updated realtime search.
