hi,
I've been recently researching about first interactive applications that placed on digital (virtual) or real platforms. Firstly I can probably say that the first interactive application was belong to 1977 year name is <a href="http://en.wikipedia.org/wiki/Aspen_Movie_Map">Aspen Movie Map</a> But there is some strange things in there like touch screen usage <em>(I mean is could be the first app?)</em>
Secondly I need "the first installation or performance". I could not find enought or exact information about that.
