The Northrups' YT channel has gained some 1.3 million subscribers, which speaks to their popularity. From my sporadic viewing over the years, I find that they seem to like to promote the 'ten best' or 'top x' of things, 'a versus b', and they litter their videos and titles with hyperbole. I guess that approach attracts viewers and subscribers, but doesn't necessarily create high-quality content that has a shelf life longer than a week. However, I've learned some things from several of their productions, so I'll give them a bit of credit.
Like many YT items, I find that the viewing time-to-value ratio is just too high; I prefer reading.
I suspect that they don't put a lot of in-depth research or analysis into their topics, and the video in question here seems to me to be a somewhat scattered collection of misnamed 'moments'. As expected, the comments from viewers present a variety of other plausible historical candidates.
For a curated and extensive coverage of the history of cameras, I'd recommend the 472-page book
500 Cameras by Todd Gustavson, then Curator of Technology at George Eastman House in Rochester NY. (2011, Sterling Publishing Co., Ltd.).
Here's a short video that has reached a fairly good viewership, but low-key compared to T&C:
