GoPro completely changed skydiving photography. Before GoPro we would fly around with camcorders clumsily bolted to the side of our head. Now they can be mounted anywhere, with greatly reduced chances of injury (a fast opening can expose you to dozens of Gs, causing severe neck injury when a heavy object is on your head). There are now a ton of options other than GoPro, but GoPro was the one that got the product/market fit first and changed everything.
