Thank you for your question! Here is your answer:
Scroll down to the bottom of the page, and it gives their annual
subscribers, along with single retail sales.
Here are the US subscription figures.
This is the advertising information for all of Hearst's magazines.
You'll find the Cosmo information on page 4. You'll need Adobe Acrobat
Reader to read the full report. In case you don't have it, here are
RATE BASE 2,600,000
JANUARY & AUGUST ISSUES 2,700,000
I searched for each magazine by name, and then looked on their web
site for "Advertising Information," or something similar. You can do
this for just about any magazine you need subscriber information for,
becuase they have to give out the numbers annually, and publish the
report in their magazine.
Thank you, I hope this helps! If I can clarify the answer in any way,
please let me know before you rate it. Thank you.
