Here's all you need to know:

I counted two public-domain videos, one BBC stock video, five public domain photos that have been pan-scanned and a text crawl. The music is from a stock library; BBC probably buys into it for $500 a month all they want. I'm no editor but I could put that piece together in about 20 minutes.

And because it's video, their time-on-site is higher, which means they get more advertising revenue.

And because it's video, it's ranked higher by Google.

And because it's video, it will auto-play on Facebook.

Is it everything that's wrong with the Internet? Well, yeah. The only way anyone has figured out how to make money on the Internet is to slather it in ads and hope the advertisers will keep paying. Retelling the MiG-25 story probably took a copy editor all day while the guy who cut that shit video probably made a dozen or more that day. I'll bet he's got a clip database that lets him drop shit into the timeline simply by searching; I've got that for sound design and I ain't the BBC.

Look at it this way: most people aren't even seeing it on desktop. They're seeing it in their feed.
