It is true that government should not be allowed a monopoly over broadcasting, but that is very rare outside totalitarian states. Usually countries have at least one privately owned broadcasting network competing with the public media and so limiting political manipulation by the State. In addition, corporatization, as with the BBC in the UK, or CBC in Canada, sets the broadcaster up as accurate and impartial, allowing for the benefits of public ownership without the risk of political interference. Instead, the greatest risk of bias lies within a purely private broadcasting sector, where the high costs of entry and technological development encourage consolidation to the point where powerful individuals, such as Silvio Berlusconi in Italy, can manipulate the broadcast agenda in their own interests. Without the balance guaranteed by public service media, meaningful participation by all citizens in the social and political lives of their societies and fair elections might become impossible.
