Info in an instant

In 2009, it's no longer enough to search for information that was current 30 minutes or an hour ago. Now, Internet junkies look for their news, Tweets and links to be updated in "real-time," just as they are on Twitter.

Search engines bought into this idea in 2009. Microsoft and Google struck deals with Twitter to pipe in or replicate its real-time search function. The micro-blogging site lets authors post short bursts of information, which become searchable the moment someone clicks send.
