Today's Tech: Microsoft to kill off Windows Live Messenger, Virgin launches TV Anywhere app, Google Nexus journey relived

Microsoft has confirmed that it will kill off Windows Live Messenger in all countries except mainland China during the first quarter of 2013. The service will be replaced by Skype, which was purchased by Microsoft for £5 billion last year. As of 2009, Windows Live Messenger had 330 million active users per month, and although this number has dwindled, in June 2011 it still boasted 40.67 per cent of the global instant messenger market share, compared to Skype’s 27.39 per cent. However, Microsoft clearly sees Skype as a platform with more potential and its own original messenger as a platform nearing its demise. The release of Skype 6.0 for Windows and Mac was the first of several moves the company will make in order to streamline the transition as much as possible.

Last week, Kim Dotcom, the founder of the defunct file-sharing website Megaupload, unveiled plans to launch a new successor using Gabon-based domain name me.ga. However, Gabon’s government says it will suspend the domain and will not "serve as a platform or screen for committing acts aimed at violating copyrights, nor be used by unscrupulous people." Dotcom's attorney, Ira Rothken, who oversees MegaUpload's worldwide defence, insisted that MegaUpload's successor site will not be available at Me.ga but added that the new service will still go ahead.

Virgin Media has released its answer to Sky Go, dubbed TV Anywhere. The new service is a website and app combo that affords Virgin customers the ability to stream content onto their mobile device or computer. The app can also let the user control their TV with a phone or tablet, allowing them to rewind, pause and change the channel with the make-shift remote. Currently only available on Apple devices, the app is free to download for Virgin subscribers.

Microsoft Windows or Apple’s OS X – which operating system is most secure?

Google's Nexus 7 tablet was recently joined by the LG-made Nexus 4 smartphone and the Samsung-built Nexus 10 tablet to round off the company's hardware offerings. But the Internet giant has an impressive legacy of collaborations with third-party electronics companies, dating back to the first Google-affiliated device released in 2008. James Laird takes us on a trip down memory lane, tracing the Nexus line's steps beginning with the HTC Dream, through to the Samsung-made Nexus S and Galaxy S, and this summer's entry-level, Asus-produced Nexus 7.
