Oh right. Yeah nah, it’s mostly YouTube videos without ads (preroll and midroll ads from YouTube, as well as sponsorship segments which are edited out). That’s the primary purpose of the site. On top of that, probably about 20% of videos have a bit of bonus content on Nebula ranging from a tiny segment of a few tens of seconds up to over 10 minutes. Then another roughly 20% of videos a released on Nebula first, often by 1 day, sometimes by over a month. Then finally there are the Nebula originals. These are funded by Nebula itself, many stay exclusive to Nebula for life, some eventually get released onto YouTube. There are podcasts too, like the Nebula-exclusive Jet Lag companion podcast The Layover, and Jason Slaughter of Not Just Bikes’ “The Urbanist Agenda” which is also available on public feeds (ad-supported, I assume—I’ve only ever listened to this one via Nebula).

If you subscribe to Nebula, you’re doing it for all of that, but also in part in the interest of supporting creators. It’s like Patreon in that respect, part of its value is the knowledge that you’re doing something to help fund the creation of the content you enjoy to a much greater degree than if you were watching ads at single-digit dollars per thousand impressions (and obviously far greater than if you were blocking ads).
