I have yet to receive a stock video licensing request for something on Netflix, but if you do, they should be top-tier rates just like any national long-format TV (worldwide rights).
This article seems to be focusing on long-format programming. Social media and Youtube still are the dominant form of day-to-day video consumption online for short-form and viral clips.
Bottom line, *online* is where the media corporations are making the bulk of money from content, and that share is only going to get larger. Again, this includes social media, the corporations of which right now are making billions off of user content and not sharing a dime of that with any creators. That's not a good thing moving forward. Posting your valuable work to those platforms natively is giving free content to what *should* be one of your primary big-ticket licensees. They are bigger today that what NBC, National Geographic or Discovery were 10 years ago! Viral images and videos are bringing in thousands (probably mid five figures and up for the more viral pieces), all going to the platform owner.
