I used to work for Activision in Santa Monica and Electronic Arts (EA) in Los Angeles.
There were no black or latino people at all in any important position throughout either company. Just to let you know. There were alot of black testers and other disposable contractor positions, but nothing more than that
In fact, I don't remember any latino or idian or anything else in the several years I worked there. Just white and asian.
I left to go to Pandemic Studios which was mostly white and asian also... but at least there were some blacks and latinos there in middle-managment and dev positions. EA eventually closed Pandemic Studios though... so yeah...
EA also used to have a 'newblack' type chick for thier human resources department, but I think she is sublet through another company or an agency or something, so even that doesn't really count.
