Back in December Google launched their real-time search, indexing up-to-the-minute conversations coming from Facebook, MySpace and Twitter.
Today they’ve announced something new: Replay.
With the advent of blogs and micro-blogs, there’s a constant online conversation about breaking news, people and places — some famous and some local. Tweets and other short-form updates create a history of commentary that can provide valuable insights into what’s happened and how people have reacted. We want to give you a way to search across this information and make it useful.
Starting today, you can zoom to any point in time and “replay” what people were saying publicly about a topic on Twitter.
Right now they’re rolling it out across the Web but say the service will be globally available over the next few days.
In the meantime you can try it out via this link. The search term we include in it is “lost” and the image below should give you a sense of how Replay can work.
Replay search using the term “lost”.
Note the mid-evening spike in the timeline? That’s when the television show was on. Otherwise, you see use of the term at low levels before and after the episode.
Try it with your product or brand see what people are saying, and when they’re saying it.
