PSBs funding sources give them an unfair advantage in the broadcasting market, harming competition.  Public ownership of the media distorts competition, harming private companies in their domestic marketplace and their ability to compete internationally. It does this because the government is funding a service that could be supplied profitably by the private sector - for example, a pop music radio station or the broadcast of sporting events. The market share of private companies inevitably suffers, along with their ability to raise advertising revenue based upon the size of their audience. This means that private broadcasters end up with less money to spend on their programmes and are less well placed to compete internationally. James Murdoch, son of the medal mogul Rupert Murdoch, in his MacTaggart Lecture at the Edinburgh Television Festival in 2009 echoed this opinion stating that the free news output by the BBC “"threatens the provision of news in Britain".
