With the great success of in-game sales of some high-flyers on the market there is also still some confusion of the terms "virtual goods" and "digital goods". Let me explain the meaning and difference of these 2 related terms:
Both terms are describing a group of files for a certain purpose. The difference is that "virtual goods" are only usable in a "virtual world". These files have no meaning in the "real world" like an antivirus tool or a MP3 file you can listen to.
That means the term describes ONLY files that are used in games (like MMO - massive multi-player online games) or virtual realities (like Second Life).
On the other hand: "digital goods" describe all downloads or "files" if you like, that have a use in the "real world". That includes photos, software, mp3 music and similar stuff.
You can use tradebit for both, but we have focussed on "digital goods" so far.
