What is the difference between a paid circulation and a controlled circulation magazine?
Also, what is controlled circulation?
controlled circulation. Distribution method in which only qualified subscribers (such as architects, engineers, or doctors) receive a publication, usually for free. Also called qualified circulation.
Furthermore, what does circulation of a magazine mean?
A magazine's circulation is the number of copies it usually distributes for each issue. Circulation is not always the same as copies sold, which is usually called paid circulation, because many magazines are distributed to readers without making them pay anything.
If you know the circulation, estimate the readership with a survey, then divide total readers by the total circulation, you can calculate the average number of readers per copy. For many monthly magazines, the average is about 4 or 5 readers per copy.
