The dominance of the BBC in the UK (over national and local rivals) has often been noted.
And this week's Newswatch suggests that the BBC is now colonising social media too:
Once upon a time, BBC News had only two means of broadcasting, radio and television. But now it is faced with a vast increasing number of ways with which to reach audiences. There is Twitter, where the BBC's breaking news account has almost 30 million followers, Instagram where more than 3 million people follow BBC News, and, of course. Facebook, where the corporation has the largest page of any news organisation in the world. In addition, it has started streaming some of it output via Facebook live, as well as other live streaming apps such as Periscope.
