Did they decide to make audio and video optical formats play from the
inside outwards?
Was it simply due to the idea of making variable sized discs? IE if you
look at, for example early copies of James Last Tango, or Roxy Music
Avalon you see that there is a huge part of the surface not used and it
can be used as a mirror. Perhaps back in the day, it was thought that one
could crop off the disc so not only could we have singles sized ones but
old vinyl album length ones as well.

Nowadays of course the whole surface looks used even when its not. Makes
you wonder if there is some secret info in those outer areas....

When analogue disc recording was in development,
it was suggested that they too should play from the inside
outwards. For classical music this would have made a
lot of sense as the final movement of a symphony is
usually the loudest:-)
