Chillingo is the publisher of multiple iOS games. They were acquired.
Rovio is most likely worth much more than $20m at this point.
Same thing, except for games.
The book writer creates the book. For an iPhone App that's the same as the game developer/development studio. Ok, got that.
The book publisher physically creates the finished product and distributes it wholesale. That's totally different to the world of iPhone apps/phone apps. The developer creates the finished product (the binary) not the publisher and there is no wholesale distribution, as you can only sell it through one place - the iTunes App Store.
So, your answer kind of makes no sense and doesn't move the conversation forward.
Rovio is still independent.
They used Chillingo as a publisher and thus they are obligated to pay Chillingo 50% of the profits for Angry Birds.
EA has purchased Chillingo and thus rights to 50% of Angry Birds's future profits.
I know they've published a number of top 50 apps, but I'm curious as to what cost.
essentially it's a crash the castle type of game which are a dime a dozen...but by branding themselves they managed to get the success they've got
Half Life 2 is just another first person shooter, they're a dime a dozen. Doesn't mean it was easy to make.
So, I guess EA's in-house "8lb. Gorilla" homegrown studio and mini-publisher for smartphones was stillborn, so they acquired one. Smart move. Chillingo has had a load of #1 app store hits from various developers; they seem to know how to pick 'em.
