From Oracle FAQ
IOUW (International Oracle User Week) was a conference jointly hosted by the IOUG-A and Oracle Corporation. These companies are now hosting their own conferences.
Almost 500 Oracle users gathered in San Francisco in 1986 for the first International Oracle Users Week (IOUW) conference. IOUW attendance continued to grow throughout the years. Oracle saw this as an opportunity to create even more marketing sessions to further increase growth. In 1996 Oracle announced that starting in 1997, it would take control of the user conference and call it Oracle OpenWorld.
The last IOUW conference was held in 2005 (the 2006 conference was cancelled). The IOUG are now involved with the COLLABORATE conference.
