Understanding Media and Culture: An Introduction to Mass Communication (to give it its full title) is a textbook, released under a Creative Commons licence by the University of Minnesota, that’s free to read, copy and share – which makes it especially useful for schools / colleges or students on a tight budget.
Under this particular licence you’re also free to adapt the work in any way you like (“remix, transform, and build upon the material”) and what this will mostly mean is that if you want to chop chapters or sections out of the textbook you’re free to distribute these in any way you like (you just can’t charge anyone for the privilege).
In terms of content, the main body of the text dates from 2010 but there has been some updating in 2016 (particularly around the impact of new technologies) which makes it pretty up-to-the-moment as far as textbooks go.
The emphasis on media and culture means that most of the text is given-over to an analysis of the cultural impact of different types of media, both old (books, newspapers, film and television) and new (video games, entertainment, the internet and social media). Each type is given their own discrete chapter which, among other things, looks at their broad development, relationship to culture and, perhaps most-interestingly, how they have been impacted by the development of new technologies.
The remaining chapters deal more generally with a range of areas: concepts of culture, media effects (there’s coverage of a range of theories dealing with direct and indirect effects), globalisation, the relationship between the media and government and a final section on the future of the mass media.
Each chapter also has its own learning objectives, brief summary and short exercises. Whether or not you find these useful is, as ever, a moot point. I’m personally not a big fan, but Publisher’s love them so we probably have to learn to live with them.
Or ignore them.
It’s your choice.
Finally, one obvious drawback, as far as UK teachers and students are concerned, is that the cultural focus is largely North American. This means that many of the chapters draw on materials and examples that will be unfamiliar to any but an American audience and UK teachers who decide to use these chapters may want to take advantage of the aforementioned editing privileges afforded by the CC license.
If you think you might be able to live with this, the textbook’s available to:
