Let's go further back in time. Software programs on NeXTSTEP have had the extension .app since the first release in 1988. There are plenty of videos around from that time in which Steve Jobs refers to software programs as 'apps'. At the time, it wasn't a common word at all with Mac and PC users. Only after Steve Jobs came back to Apple, it entered Apple vocabulary because he would refer to software programs in that way.
Also, Sage didn't use the name as their attempt to revive their trademark application, which in their filing they describe as "International Class 035: Operating on-line marketplaces for buying, selling and exchanging computer software and on-demand applications", was denied. In 2006.
[edit] I could buy apps for the archimedes in a store. An app store is somewhere to buy apps. Technically speaking the apple app store is a package manager with ecommerce functionality. Very much like the linux predecessor CNR, in other words. http://en.wikipedia.org/wiki/CNR_%28software%29
[edit] Wikipedia, that fount of shaky, but vaguely accurate hearsay says that RISCOS was released in 1987. Archimedes computers were widely used in the UK due to being in pretty much all state high schools. Steve was not responsible for bringing the word into the public domain, no matter how much you wish it so.
That's not to say that the separate components of Apple's App Store were particularly novel. Before its launch, there were package managers, there were online marketplaces for software, and the name 'app' had already been used by several platforms. Apple united those ideas, made it a user friendly environment, made it easy to buy apps with one click (using the credit card that was already on file in iTMS), and integrated the update process. That's often how Apple gets their successes, by combining and improving on existing ideas (see OS X, iPod, iPhone, iPad, etc.)
I never used Acorn's Archimedes, but growing up in The Netherlands, the first computers I used were Acorn Electrons, our primary school classroom had six of them. That's how I started programming, in BASIC, at the tender age of 6. I have fond memories of using those machines.
