The Red Bulletin is a handsome Web and print magazine that practically oozes testosterone. Recent issues have featured stories on the world's deepest free diver, human-pyramid building in Spain and a guy who rappels into volcanoes. All of it is embellished with photography worthy of Sports Illustrated.

The printed Red Bulletin reaches 3 million readers a month, according to a spokeswoman, which almost matches Sports Illustrated's subscriber total. Not bad for a publication that's barely 5 years old.

The most interesting thing about the Red Bulletin, however, may not be what it is but who publishes it. The magazine is owned and edited by Red Bull GmbH, the Austrian-based marketer of Red Bull, the ubiquitous "energy" drink. The company started the magazine to help reinforce its self-created image as a live-at-the-edge brand for the young men who guzzle its primary product. So is the Red Bulletin marketing or journalism? The answer: both.
