The flash drive in my opinion has had the greatest impact on the film industry because before they were invented, people had to film on tapes or VCRs and things like that. It was very easy to lose footage on those, either by accidentally erasing it, or physically damaging the tape, among other ways. Those issues are much less likely to occur if you're filming on a flash drive or SD card or other modern inventions such as those.
Technicolor by Walt Disney. I think this because color makes me feel like the movie is more real, and without color you couldn't see the blood in horror flicks.
