DVI connectors offered analog VGA for years. This meant that graphics card vendors could put one port on their card that did both, huzzah, and a passive adapter got you VGA out of DVI.
DVI is ahead of DisplayPort by 8 years. The DMCA is passed and HDCP becomes a Thing. Many card vendors do put DisplayPort on their cards, since it's the "Professional" standard for video, but that isn't until 2008 or so. DisplayPort would not be widely adopted until 2012-ish.
Fast forward, VGA dies. DisplayPort and DVI-Dual link are there. DVI Dual is forwards-ish compatible with upcoming HDMI displays for TVs, as pushed by the MPEG-LA and DVD makers. In 2009, less than 5% of devices shipped had DisplayPort on them. DisplayPort at this time also cannot handle the two most popular color spaces in use: sRGB and Adobe RGB 1998.
Part of the issue was a perception thing: Displayport was widely adopted by Apple early on, and consumer understanding of Mini DisplayPort was that it was an Apple standard, rather than an open standard, and this further pushed the port out of the limelight.
