Press Barons: End of an Era?

The capo di tutti capi of the world's media moguls, Rupert Murdoch, has been the subject of much press coverage this week with a claim that he's not a fit person to run an international corporation but that isn't the biggest threat his newspaper business faces. Justin Rowlatt and his guests, Carla Buzasi, editor-in-chief of the Huffington Post UK, Kalpana Sharma, a former editor of the Mumbai edition of the Hindu, and Tom Rosenstiel of the Pew Research Centre in the USA discuss whether press barons like Mr Murdoch are an endangered species. Should we care if they face extinction? Plus why free online news isn't really free at all.
