HTC= ICI (well HiTech & Pyro anyway)
ICI & DoMark created Confirmed Kill, later to be renamed to WarBirds when DoMark and ICI split. DoMark took the wonderful graphics engine (for it's time) and name, ICI got everything else.
They reworked it quickly, and the next version had a different terrain and name.
From there, ICI was bought out (or sold to by Wild Bill) by IMoL Interactive Magic OnLine. Which, I believe, was a subsidiary or a branch of iEN.
A bunch of stuff happened, more people were hired on to help the development of WB... plus they had to get some other guys on board for Mac Devel and stuff like that.
Dunno the exact transpirings, but the current HTC team (minus Aerilius) left iEN and began work on AH. While iEN still owning WB, began work on reworking it.
And that's where we are today.
