I believe that one of the most useful online source to use when studying the society and its relation with the media is YouGov: https://yougov.co.uk. It is an international internet based market research firm with operations in Europe, North-America, Middle-East, Asia-Pacific and Africa. It was founded in the UK in 2000, where its main headquarter still is, and after 5 years it became a public company. Its motto is What the world thinks and it is a member of the British Polling Council, association of market research companies whose opinion surveys are regurarly published or broadcast in media in UK.
Starting from their surveys and polls, they publish articles about politics, lifestyle, economics, consumer trends and much more. It is very reliable and I found it truly interesting and useful when writing essays. In fact, it is possible to find a survey about every current and past matter to use as trustable source.
There is also a fascinating section called “YouGov profiles”, where selecting a brand of any kind, it is possible to see the profile of an average consumer. I found this section truly useful when I was selecting the target audience of PR and Advertising campaigns I was working on during the first semester. Here an example of the average profile of The Guardian readers:
I leave you with one of the article they published last year, based on a survey that shows that British people trust more Wikipedia than journalists. I believe that it can be an interesting reading for us that we study media and how the society relate to any sort of it: https://yougov.co.uk/news/2014/08/09/more-british-people-trust-wikipedia-trust-news/.
