MTV Multiplayer reveals Sony started charging PlayStation 3 developers for downloable content (DLC) on October 1, 2008. Publishers who wish to offer free downloable content through the PS3's PSN online store are required to pay 16 cents per downloaded gigabyte during the first 60 days of the content's release:
MTV Multiplayer has verified that a letter sent to publishers last fall detailed the policy. It applies a 16-cent charge to every Gigabyte of content downloaded from the PS3’s PSN online store. For free content, like demos, those charges apply only during the first 60 days of the content’s release. For paid content, like map packs, the charges rack up in perpetuity, or until that content is removed from the PlayStation 3’s online store.
This “PlayStation Network Bandwidth” fee has been unpopular with game companies, according to at least three publishing and development sources who spoke to MTV Multiplayer about the policy on the condition of anonymity so as not to get their companies on Sony’s bad side.
