Couldn't see any mention of this on GAF anywhere, but there's a website called MK Secrets that have been producing their own unofficial historical webseries detailing all things Mortal Kombat, from development to merchandising and story canon. It's still ongoing and has been running since 2011 apparently (I just found out about it yesterday). There's some annoyances throughout, like the narration synthesizer that can be a bit wonky at times and some opinions being presented as facts of dubious nature, but all in all I found it to have pretty good production values and tons of interesting footage and kontent.
The History Of Mortal Kombat: Episode 01 - The Beginning (Mortal Kombat I)
The History Of Mortal Kombat: Episode 02 - Nothing Can Prepare You for This (Mortal Kombat II)
The History Of Mortal Kombat: Episode 03 - There is no Knowledge that is not Power (Mortal Kombat 3 / UMK3)
The History Of Mortal Kombat: Episode 04 - The Year of Mortal Kombat and Beyond (Mortal Kombat The Movie / MK Live Tour / MK Trilogy / Defenders or the Realm)
The History Of Mortal Kombat: Episode 05 - Darkness Is Calling (MK Mythologies / Mortal Kombat 4)
The History Of Mortal Kombat: Episode 06 - Soul of a Warrior (Mortal Kombat Conquest / Mortal Kombat Gold / Mortal Kombat Annihilation)
The History Of Mortal Kombat: Episode 07 - Descent into the Underworld (Mortal Kombat: Special Forces / Mortal Kombat: Federation of Martial Arts / Mortal Kombat: Advance)
The History Of Mortal Kombat: Episode 08 - A Deadly Alliance (MK Deadly Alliance / MK Tournament Edition)
The History Of Mortal Kombat: Episode 09 - Deception, It's in Us All (MK Deception)
I enjoyed the Special Forces episode particularly, but that's due to my own facination with that game's history. In fact one of my first assignments in game journo was to write a blurb about that upcoming game as an intern. All I was told was that it was a Tomb Raider knock off and I should write something about how MK sucks. I remained a bit more neutral in my approach, I recall.
The site itself offers downloadable versions, some of which have some fixed audio issues from the Youtube versions. http://www.mksecrets.net/
There's also a short series by the same guys surrounding rumors and undiscovered secrets to MK called Mortal Kombat Haziness
