CNN vs BBC

The BBC and CNN are both very different companies, apart from the fact that one is British and one is American, they also have many other differences.

Firstly, BBC is a public service broadcaster, and is operated under a Royal Charter. The BBC is funded principally by an annual Television License Fee, which is charged to any household, company or or organisation which uses any type of equipment to to receive live television broadcasts.
The CNN is owned and run by the Turner Broadcasting System division of Time Warner.

As Charlie Brooker points out in his 'Charlie Brooker On British And American TV News' video on YouTube, British & American news is reported very differently.
British news channels such as ITV & BBC, normally use male presenters in two ways, either with a very stern, serious personality, or with a very laid back, casual personality. Brooker also tells us that he has noticed, female presenters are usually young and beautiful, especially if they are part of a duo. He also points out that the male/female duos usually represent a dysfunctional couple, or a young intern with a man that is grooming her.
However, American news channels such as Fox & CNN, use males presenters that have a strong opinion and seem slightly 'crazy' as they can sometimes shout a lot and shove their viewpoints into everyone's faces.
