With thanks to
Conal (who spotted this through
Twitter and
Instagram accounts/feeds linked to his joint Lady Gaga production before I heard about it through reading
the Guardian report the next day!), here's a really useful resource for quickly getting a grasp of the difference between newspaper readerships.

Magazine + newspaper publishers' audience profiles are more accurate (advertisers need to know who they're paying to target!), if not always so detailed as this, but
the YouGov data, which takes in some major artists as well as covering a variety of media (such as
newspaper readerships), is certainly worth a look.
