Keep in mind that most inventions aren't "the first X", but "a better X" or "an X that can Y". You're going to see a lot of incremental improvements that you likely won't care about on a personal level.

With motion pictures, you've got a similar story (though Le Prince was at least taking steps towards delivering).
With the light bulb, Edison's version -was- more practical -- unlike Swan's, it could be used on a larger scale and could last a reasonable amount of time.
