Two reasons can be given for this, the first being their low circulations.

We can break even on a much lower circulation and that's what our economic model shows.

The book came out in 1922 and has been in very low circulation ever since.

On October 1, a low level circulation developed in association with the convection.

By August 2, a low level circulation was present.

By June 19, a low level circulation formed as the system moved westward.

It rapidly weakened over India, and lost its low level circulation on the 2nd.

On August 15, limited outflow was witnessed over its low level circulation.

The low circulation - only 750 copies are printed - means that the newspaper doesn't have to be registered as part of the media.

Progressing northwest, this low level circulation maintained its identity for another couple days.
