Quizlet on music magazine's institutions

I have created this Quizlet to teach myself about the publishers of music magazines- when they were founded, what they do and their history. It also taught me that some magazines have the same publishers, for example Q magazine and Kerrang! magazine have the same publisher- Bauer. This is interesting, as they are different genres, which shows that one publisher can publish multiple music magazines, for different purposes/genres. I also learnt that some institutions are family run/founded, and some were founded by one individual e.g. Wenner Media LLC was founded by Jan Wenner and Bauer was founded by Rudolph Bauer and is still run by the Bauer family. I also learnt that the institution can have an influence over the content. For example, the Rolling stones magazine focused on music, while it also had a political approach, which is why the founder created a Bureau. I also learnt that some publishers publish many other magazines/forms of media, while others publish just a few. For example, Bauer only publishes multiple magazines, while Prometheus Global Media only publishes on other magazine- the hollywood reporter.
