GoPro is the brand that defines the action camera. Many people I know, to my frustration, still call all of the neat little actioncams devices "GoPros" even when they're made by DJI, Insta360, or one of the other rival manufacturers. That is the kind of brand success that belonged to tranformational devices such as Sony's Walkman or Apple's iPod.
Now, though, like those products before it, the GoPro is struggling. There is less need for it, and those competitors have gotten good.
