A Little Long But Here Is Some History.
I've always said there are two facets to the modern drone - the flying and the camera. As an RC pilot, I'll always remember the first time I commanded something (fixed wing) in flight . . . successfully? From that day forward the thrill was always there, but over the years that feeling needed to be recharged by reaching new goals in flight. Most drone pilots today, are getting that 'high' from the flying and I totally get that. But as some may find, adding that new component can be a whole new experience and as many will see; the photography or video side of 'drones' is a whole hobby/profession in and of itself.
Some backstory. In the mid 90's, a friend who was an RC helicopter pilot and I decided we would try and start an aerial photography business - and this was waaaaay before the FAA had put any limitations or exclusions to commercial flight because there was really no one doing it since the technology wasn't there. This was about 12 or 13 years before the emergence of the "GoPro" and about 15 years before the first commercial drone with camera.
I designed a 2 axis gimbal (non stabilized but servo driven) that would hold a full size DSLR which happened to be slightly more weight that the helo
should have been able to carry.

This helo had a rotor diameter of around 75 inches and was driven by a 38cc gas engine - fairly big for it's time. The truth is; it could lift and hover the load in good conditions (low wind, low heat) but as we found with even slight wind and high temps (we were in South Florida) these conditions almost never existed. Typically we had a max of about three minutes before over heating and loss of power would force a landing. Needless to say; that business went nowhere. I mean, a 25 pound lawn mower with a 75 inch cutting circle - yeah, lets take this into a neighborhood and shoot photos!

?
But the idea of marrying a camera and an aircraft was not over and I had several attempts at a similar rig, mounted to various fixed-wing planes that could lift the load, but due to having NO screen to see what the camera was seeing (miniature signal transmission like we have now did not exist) therefore rarely did the shot ever come out composed anywhere near right.
The search for smaller cameras inevitably led to pay dirt - sometime around the late 90's early 2000's - CVS Pharmacy's began selling these little video cameras that were not much bigger than a GoPro. Actually they weren't selling them as much as they were
renting them. The way it worked was like this - these cameras were video only, you turned it on and hit 'record' and it would do so for about 45 minutes and once it was full, you would take the camera back to CVS and they would plug into the camera with a special connector and off load your clip(s) and put them on an SD card and keep the camera and they would just recycle. So, for about 26 dollars you had a little camera that could capture a whooping 480 (interlaced) footage of up to about 45 minutes and you could make one long clip or several short ones! And keep in mind, video cameras at this time were two to three times bigger than most DSLR's - the miniature camera boom had still not started in earnest.
Well, well. It didn't take long before we had to tear open one of those cameras and figure out what was what - and we did. And once we did, the possibility's became endless. One of my jet buddies and I decided to go and raid our respective CVS's of about a dozen of these little cameras. The deal was that if you broke or lost the camera, that was okay, you could buy (oops - rent) another. We guess CVS had a business model that allowed for losses.?
Once we figured how to offload from the onboard memory and reset the camera we were off and running. There was one summer I remember where Jay and I put five of these little cameras on
each of our jets and flew missions were we tried to capture in flight video of each other and there were times when we did; and the footage was STUNNING - again this was a time when there was nothing (at least in the consumer world) that could get footage like this. I made several videos with this footage but sadly never uploaded anywhere, as Youtube was not yet around, or I hadn't heard of it yet.
But without a doubt it was right around this time that things started happening that led to the modern Drone. I remember when I saw the first quad show up - they were little more than trinkets to us at the time. Our thinking was; it had no payload, was very slow, couldn't fly in wind or very long and certainly did not carry a camera - so as a flight-only platform, it did not appeal to any of us "real" flyers.

(that emphasis) was to show that we didn't see what was coming - but we should have.
It was not until the first commercial drones with cameras showed up that we started to take notice. Keep in mind - a fixed wing aircraft had many limitations as a camera platform, and one of the biggest is that it moved too fast and certainly could not stop in mid air and let you frame a shot. When the DJI Phantom 1 hit stores, everything changed, and suddenly the world of aerial video began to show up on sites like youtube, and though the shots were crude and un-stabilized (still no 3 axis gimbals) but the view from above was great AND, these things flew themselves! This is important to understand - never before was there a craft that had all the tech married into a single package - an aircraft with all of it's gizmos, keeping it level and in place until commanded to move, and it had a camera that a pilot could control - in FLIGHT! Even though seeing what the camera sees was still a few years off, this was groundbreaking.
By 2008 or so, the final piece of the puzzle brought it all together, and IT is the unsung HERO of the modern drone - the 3 axis - stabilized camera and gimbal. It was at this point that the true marriage of flight and camera began. In 2009 I had to have one of these things so I got a DJI Phantom 2 with the Zenmuse 3 axis gimbal for GoPro Here 2. The video and pictures were awesome but even then - the ability to have a real time view of what was going on was still a little ways away from the consumer drone market. Within a month I saw that you could buy a transmitter and receiver for the video and kits were available to allow you to splice into the drone's wiring to hook up the transmitter and you had to build your own ground station but it could be done. All in I think I spent about 1800 bucks on that Phantom 2 rig with all the video gear, camera, batteries, hard case and so on.
I still have that Phantom2 and when I compare it to my current Typhoon H Plus it's hard to believe how far the tech has come in such a short time. And during that same period, the leap from a 480 interlaced standard for video through 540, 720, 960 to the (then penultimate goal) 1080 - but in the blink of an eye as if in a time warp, the industry decided to make the next jump without rest - to 4K and beyond. The standard for video for nearly 70 years quadrupled in less than a generation.
I would say that we were exactly in the right spot at the right time to take a heck of a ride.
