Network effect

There's a lot to be said for the network effect. Case in point, GoPro. Early movers in the "action camera" space, they became ubiquitous. There's thousands of options for basically every accessory imaginable. Different mounts, including the specialized MyPilotPro Swivel GoPro Airplane Mount. Different battery pack options (like the Wasabi Power Extended Battery for GoPro HERO3, HERO3+ (with Backdoors) I use with the camera I hang off the MyPilotPro mount). Etc., etc., etc.

Then there's the Panasonic HX-A1:

This coulda been a contender. I picked one up to clip to things relatively unobtrusively. The original idea was to be able to do POV shots using the head mount:

But the one I ordered never shipped, and then eventually the order was canceled and refunded. The built in battery life is pretty anemic; there was an extended battery, but it's no longer available.

Orphaned tech. My old GoPro Hero 3+ cameras (Black and Silver) will run for a long while with aftermarket components even once GoPro itself stops supporting them, because, network effect being what it is, there's a huge marketplace for those aftermarket suppliers to tap into and incentive for them to sell products that integrate with that large installed base.

Alas, not so for the poor Panasonic HX-A1.
