"Google also announced that real-time news from Twitter would start appearing in its search results, following a deal struck with the microblogging service in October, just hours after Twitter signed a similar agreement with Bing, Microsoft's search engine. "Now, immediately after conducting a search, you'll be able to see live updates from people on popular sites like Twitter and Friendfeed, as well as headlines from news and blog posts that have been published seconds ago," said Google in a statement.
