Videos are more relevant to rewatch than articles are to reread. One needs to output more articles than videos, because articles must be "fresh" or you'll lose an audience. Nobody is printing 40 year old news - people are still watching 40 year old movies.

Playing devil's advocate here. Pricing for many online goods is almost completely arbitrary and varies with little accord to service/product quality or even what that service provides.

Another related example of arbitrary pricing: people will pay $2 for a soda from a vending machine but won't pay $1 for a useful app on their phone.

There's something going on there... The sooner the $1 app's figure out what makes people buy $2 sodas is the day they become rich. And the sooner content providers figure out why people will pay $20/month to stream media (Let's say $10 to Netflix, $10 to Spotify or something) and charge people $20/mo for their articles... things will turn around for them.
