When you’re talking historical data for social intelligence, there’s probably no better source of information than Twitter. But as the service grows and changes, there’s been a veritable brick wall in the timeline – 30 days. Social data provider Gnip was one of the chosen resellers for historical Twitter data, but it could only go as far back as one month. Today that changes as Gnip’s Twitter reach extends to Twitter’s opening in March of 2006.

The company has been in an “early access phase” for the past few weeks, providing data to brands like PayPal, Esri and Waggener Edstrom. Today’s announcement brings Twitter data in parity with what the rest of Gnip’s offerings from Tumblr, Automattic and Disqus.

Today’s announcement allows Gnip to leapfrog its competitor DataSift as far as its reach is concerned. In February of this year TechCrunch reported that DataSift would have access to historical Twitter data going back to January of 2010, but that still left four years of Tweets without access outside of Twitter itself.

Reading a case study, Union Metrics says that its TweetReach product now has the door opened to “long-term research projects to competitor and share of voice analysis.” It’s fairly easy to see what advantages today’s announcement give Gnip and its customers in tracking Twitter history.
