As widely reported by the global media, including the BBC, Google has launched a real-time search service as part of its main search results, giving users access to information that has just been published from various sources, such as news, social networks and Twitter (as they announced recently).

Google says that this information will be taken from over a billion pages on the web and reflects the changing nature of content and search on the web. The announcement was made at a special event staged at the Computer History Museum in California, where Google said this was the first time that any search engine has integrated the real-time web into its results page. The new real-time search will also be available on phones and is being rolled out now.

Google's vice-president of search Marissa Mayer was quoted as saying: "This is a technical marvel, getting all these updates in seconds, making them searchable right after they are posted and making them available so that anyone in the world can find them. The updates (on Twitter) are so truthful and so in the moment. That is a really, really powerful part of this. Are you at this event right now? Are you on this ski slope right now? And because of that 'right now' element of it , this is hugely valuable data".
