Started in March 2000, the site has expanded to contain a wide range of information on the subject of digital video encoding and DVD backup (or ripping).{{cite news|last1=Woodward|first1=Matt|title=7 codec round-up at Doom9|url=https://arstechnica.com/uncategorized/2003/05/305-2/|accessdate=22 November 2017|publisher=Ars Technica|date=5 May 2003}}{{cite journal|title=Cat and Mouse Copy Protection|journal=Maximum PC|date=May 2007|pages=27|url=https://books.google.com/books?id=PQIAAAAAMBAJ&q=doom9&pg=PA27|accessdate=22 November 2017}} The most popular sections of the site were the guides to DVD ripping and the annual codec comparisons, where popular digital video codecs were compared on the basis of quality, speed, and compression. The forum is frequented by many developers of the tools and codecs featured on the site,{{cite news|last1=Kirk|first1=Jeremy|title=Hacker strips DRM from streaming Netflix movies|url=https://www.macworld.com/article/1059410/netflix.html|accessdate=22 November 2017|publisher=MacWorld|date=9 August 2007}} such as FairUse4WM.

The VirtualDubMod project began after many modifications to VirtualDub were posted on the Doom9 forums.{{cite book|last1=Buechler|first1=Georgios Diamantopoulos, Sohail Salehi, John|title=Learning VirtualDub the complete guide to capturing, processing, and encoding digital video|date=2005|publisher=Packt Pub.|location=Birmingham, UK|isbn=9781847190246|edition=1st|url=https://books.google.com/books?id=apiArMc8t9MC&q=VirtualDubMod+project+doom9&pg=PT42}}

Doom9 gained notoriety due to its involvement in the AACS encryption key controversy. The utility BackupHDDVD was first posted by a Doom9 poster using the alias muslix64.{{cite news|last1=McMillian|first1=Robert|title=Hacker: Blu-ray, HD DVD copy protection cracked|url=https://www.infoworld.com/article/2659617/security/hacker--blu-ray--hd-dvd-copy-protection-cracked.html|accessdate=22 November 2017|publisher=Info World|date=29 December 2006}} The earliest information on how to find title and volume keys was also first revealed on Doom9 forums, by other users.
