What industry needs technical innovation?
pg: Presumably the fields that need innovation most are those that have some artificial constraint suppressing it.  E.g. the music business, because anything good is ipso facto sued out of existence.  Or the nuclear power industry, because the level of regulation becomes a barrier to entry to all but companies so bureaucratic they fit the government like a mold.So oddly enough, you're most likely to be able to achieve innovation where other people are.
