ownership and regulation

How many organisations own national newspapers and do any companies own more than one title? 

Mirror Group - The Mirror

News International - The Sun, The Times, The Sunday Times

Northern and Shell - The Daily Express

Press Holdings - The Telegraph

Pearson - Financial Times

Trinity Group - The Leicester Mercury

Both The Guardian and The Observer are sister newspapers so therefore, have the same political alignment of being left wing and produce very similar content. 

News International have ownership of the trio of The Sun, The Times and The Sunday Times, and implement right wing views on each of the newspapers but their content does differ quite a bit, with The Sun being a gossip based tabloid newspaper and The Times and The Sunday Times are broadsheet newspapers, all of which are owned by News International who themselves are owned by British entrepreneur Rupert Murdoch. After the negative attention the company received from the Leveson Inquiry, they subsequently changed their name to News UK. 

Considering more media industries are following the normal capitalist pattern of increasing concentration of ownership in fewer and fewer hands, this is leading to a smaller variety of opinions represented and a pursuit of profit at the expense of quality or creativity.

Ownership may be something that is a cause for concern in the UK because if one company hold too much power and owns too many popular news outlets then consumers will only be subjected to one opinion, rather than a variety like there should be. Small numbers of different owners of outlets mean that quality and creativity will be neglected when producing the news because the owners only have one goal in mind: profit.

Companies owning other media outlets:
The owner of Leicester Mercury is Trinity Mirror the largest newspaper company, they also own other newspapers like: Daily Mirror, Sunday Mirror, Sunday people they also own regional newspapers such as, Birmingham Mail,  Manchester Evening News and some other popular ones.
