MUMBAI: Facing heat over alleged use of piracy to scuttle business of pay-TV rival ITV Digital, News Corporation CEO Rupert Murdoch vented his anger on social networking platform Twitter by terming the allegations as baseless.

"Seems every competitor and enemy piling on with lies and libels. So bad, easy to hit back hard, which preparing," Murdoch said on his Twitter handle @rupertmurdoch.

According to a BBC Panorama documentary, a company part-owned by News Corp carried out hacking by obtaining codes belonging to ITV Digital and posted them to allow viewers to watch for free which finally led to the demise of Sky?s main digital TV rival, ITV Digital.

NDS, which manufactured smartcards for all News Corp pay-TV companies across the world, said that Thoic was legitimately used to gather intelligence on hackers while Gibling worked as a consultant.

The publication of codes resulted in widespread piracy which finally resulted in the demise of ITV Digital, which had been set-up by Britain?s leading free-to-air commercial broadcaster, in 1998.

In a statement late on Wednesday, News Corp President Chase Carey said the BBC programme presented "manipulated and mischaracterised emails to produce unfair and baseless accusations", and he backed NDS?s call for the publicly owned British broadcaster to retract them.

The piracy scandal came as a second blow to the already beleagured News Corp as it had hardly recovered from the phone hacking scandal involving its UK publishing unit, News International.

The media conglomerate is under tremendous pressure as it is already under television regulator Ofcom?s scanner which is scrutinising whether James Murdoch and News Corporation are "fit and proper" persons to be in control of BSkyB, the company that runs Sky TV.

MUMBAI: UK broadcaster Channel 4 has announced that it will launch a new channel called 4Seven, which will have scheduling based on how much chatter programmes are getting through social media outlets. It will allow viewers to catch repeats of shows.

4Seven will be launched later this year. It will schedule content that is creating noise - among commentators, bloggers, Twitter , Facebook.

The aim is to deliver more content that viewers want to watch. Channel 4 CEO David Abraham said that viewers say that they sometimes just miss the best stuff, despite their PVR and VOD.

"4seven will give viewers more chances to catch the most popular and talked about Channel 4 shows from the last seven days," added Abraham.
