Talks between Google and Twitter to reinstate real-time Social Search of the micro-blogging platform's posts appear to be in deadlock, with neither company able to agree a deal.
Until a deal between the two companies expired in July 2011, Google users were able to see up-to-the-minute tweets from the social platform that matched their keyword search, alongside the usual results from the web.
But as the UK's Telegraph newspaper reports today, negotiations to restart the service appear to be stalled.
Twitter CEO Dick Costolo told the paper at the Web 2.0 Summit in San Francisco that talks with Google had so far failed to reach any agreement.
"We [Twitter and Google] just can't agree on what the appropriate value exchange is. And I don't mean that in terms of dollars...There are all sorts of details that we couldn't come to grips with."
The two companies originally announced the partnership to provide real-time results at the same conference two years ago.
