By September 1999 Gej had achieved his goal of using a high performance
codec in combination with the AVI container, and
DivX ;-)
(the emoticon a jibe at
a now failed protected DVD rental system launched by
Circuit City
) was
unleashed upon the Internet. Boasting compression ratios over five times
superior to the technologies used in conventional DVDs, DivX ;-) would allow
entire movies to be transferred to single compact discs or distributed over high
speed connections in a matter of hours rather than days.
DivX ;-) gained a cult following amongst the internet underground almost
overnight. Within days of the first DivX ;-) release it became possible to download
entire feature-length videos online for the first time, and DivX ;-) was well on the
way to becoming the MP3 of video.
But DivX ;-) was just the beginning. Intrigued by the possibilities of video
compression and not ready to retire and rest on his laurels, Gej quickly dropped
the winky face and began the long process of creating a new codec entirely from
scratch.
In May 2000 Gej became co-founder of
DivXNetworks
, together with CEO
Jordan
Greenhall
, Director of Product Management
Joe Bezdek
, R&D director
Darrius
Thompson
and Vice President of Operations
Tay Nguyen
.
Soon thereafter, DivXNetworks covertly launched a website known as
ProjectMayo
that in early 2001 would become the stage for creating
OpenDivX
-
an open-source development project that invited developers and video engineers
worldwide to become part of a collaborative effort to create a free, open version
of DivX. This would ultimately become the foundation of the XVID project.
Meanwhile, DivXNetworks secured approximately $5.6M in funding from
investors and began internally developing the future of DivX technology.
By August 2001, DivX 4 was born. A proprietary codec based on the international
MPEG-4 standard, DivX 4 became the first in a long line of DivXNetworks
releases, culminating in the commercial release of DivX 5.0 in March 2002.
Since that time DivX has gone from strength to strength - a patent-pending
technology that is constantly evolving in terms of the performance, quality, and
features. DivX 5.1 sees the ultimate culmination of this work.
