Dave Lee reports:
Companies are now able to search and analyse up to two years of Twitter updates for market research purposes.
Firms can search tweets back to January 2010 in order to plan marketing campaigns, target influential users or even try to predict certain events.
Until today, only the previous 30 days of tweets were available for companies to search. Regular users can access posts from the past seven days.
UK-based Datasift is the first company to offer the archive.
Its existing customers will be able to use access “historical” tweets from today, the company said.
“No-one’s ever done this before,” Tim Barker, Datasift’s marketing manager, told the BBC.
“It’s a brand new service that we’re bringing online – it’s a massive technology challenge because of the amount of data that is pumped out every single day.”
