[EVE Online] EVE Online has this print magazine you can subscribe to, called EON. In the first issue, they offered advertising to the various corporations in-game. It was a new way to try to expand your corp. Understand, this is a real magazine – delivered to your home.
The devs just announced that they will be selling ad space in the future issues. But get this, it will cost you ISK (the in-game currency of EVE). In fact, it appears to cost you 200 million ISK to place an ad. Now that is a bit of a twist, right?
