How has news changed in the last 20 years, considering institutions and audiences, who has benefited the most?

In 20 years news has changed vastly, in terms of the way the audience can access news it has developed a great deal. News was only available in the print form of a newspapers for a very long time, then developed with technology onto TV news. TV News was launched in the 80's and then came the introduction of 24 hour news from CNN. This was a huge step from newspapers and daily news at certain times to having news available 24/7 non-stop and on teletext. 

Internet was available in the 90's and has changed and developed into a more convenience use and a easy to access form of news. Newspapers have also moved to online sites and many people get news from search engine Google News, BBC website and even social networking such as Twitter. 

Due to internet news and the wide range of knowledge and coverage it brought to the audience affected and was the cause of the fall in newspaper circulation and also caused loss of advertising revenue. Newspaper such as Metro and Evening Standard have their newspaper for free after noticing a decline in purchases and to prevent a further loss of advertising revenue gave their newspapers for free. Giving it for free at stations in London increased th amount of people reading the paper and therefore meant the cost of advertising in the newspaper to rise once again. Newspaper sites such as the Daily Mail have pay walls for online sites which audiences pay for on a weekly basis even through the view that people hold of how news should be free. 

The transformation from teletext to the button shows how the only source of 24 hour news audiences had was through digital news board to the red button on the majority of TVs ensuring easier to use and wider variety at peoples reach.
