World Stock Exchange.
World Stock Exchange (WSE) is a virtual securities exchange developed for use in the virtual world of "Second Life". The exchange provides "Second Life" companies with the ability to raise capital from the global investment market using the in-world fictional Linden currency and the new World Internet Currency(WIC).
The WSE has been surrounded by controversy since it began operation. Due to the difficulty in regulating "companies" that trade on the exchange, there have been a number of "CEOs" who have run off with IPO funds, leaving investors with nothing. Other issues, such as security and downtime have plagued the exchange, including the theft of funds by an "employee" who "hacked" the system and left with stored funds.
Operated inside "Second Life".
These are businesses and organizations originating in real life that have operated in "Second Life" and were not founded specifically for "Second Life", but have involved themselves in the world.
