What Inspired Hank Green To Start Science Communication Videos?

One of my favorite YouTube origin stories feels like watching two brothers turn a personal challenge into a community heartbeat. Back on January 1, 2007, Hank and his younger brother John launched what would become 'Vlogbrothers' with a video project they called 'Brotherhood 2.0'. The basic idea was really simple and incredibly human: they vowed to stop communicating by text and email for a year and instead post video responses to each other. That constraint pushed them into candid, often hilarious face-to-camera conversations about life, books, music, and whatever odd topic caught their fancy that week. I got sucked into their early videos because they were raw and honest — low-budget webcams, quick edits, inside jokes that made you feel like a fly on the wall. Hank's energy is contagious: he combined curiosity, humor, and a knack for storytelling, which hooked viewers fast. What started as an experiment morphed into something larger when the viewers showed up and called themselves 'Nerdfighters'. They developed catchphrases like 'DFTBA' and took collective projects seriously. Over time, the brothers spun off all kinds of initiatives — 'Project for Awesome', 'VidCon', educational shows like 'Crash Course' and 'SciShow' — but it all traces back to those first few months of mutual video letters. If you watch early 'Vlogbrothers' clips now, it’s like peeking at the genesis of a community that treasured curiosity and kindness. Hank didn’t just start a channel; he helped plant a culture that turned casual viewers into an active, creative crew. That grassroots vibe still shows up whenever they rally people for a good cause, and that’s part of why I keep coming back to their channel even years later.

I get excited every time the community rallies behind another charity drive, so here's how I usually explain it: Hank Green doesn’t run a fixed list of causes under the Nerdfighter banner — instead, Nerdfighteria primarily channels its charitable energy through the annual 'Project for Awesome' and the volunteer-run 'Foundation to Decrease World Suck'. Those two vehicles let hundreds of nonprofits benefit each year, and the specific roster changes as the community nominates and votes for organizations. From watching multiple years of P4A, I can say the kinds of groups that often show up include international health and development groups, literacy and education charities, clean water projects, and emergency relief orgs. Examples that have appeared repeatedly in campaigns or that Hank and John have highlighted over time are 'charity: water', 'Doctors Without Borders', 'Partners In Health', 'Save the Children', 'Worldreader', 'Room to Read', 'Kiva', and organizations tackling malaria or refugee crises. But note: the yearly slate is crowdsourced, so smaller grassroots groups often get spotlighted too. If you want a definitive, up-to-the-minute list, I usually point people to the 'Project for Awesome' site or the Foundation to Decrease World Suck’s pages during P4A week — they post the nominated charities and donation links. It's one of my favorite parts of the community because it’s participatory and always surprising who gets helped next.

I get nerdily excited about this kind of tally, so I did a little mental spreadsheet for you. If you add up the big YouTube channels Hank has founded or fronts, plus his personal social accounts, you land in the ballpark of tens of millions—but the exact total bounces around with every new subscriber. Roughly speaking (using public channel sizes from around 2023–2024 as a guide): 'CrashCourse' is in the low double-digit millions, 'SciShow' sits in the high single-digit millions, 'vlogbrothers' and 'Hank Green' (his personal channel) are a few million each, and a handful of related channels like 'SciShow Psych', 'SciShow Kids', 'Eons', and 'Healthcare Triage' add several more. On top of YouTube you’ve got social followers — Twitter/X, Instagram, TikTok — which together tack on a few million more. Tallying everything conservatively gives me a rough range of about 35–45 million subscribers/followers across the major platforms tied to Hank and the networks he helped build. If you want the current exact number, I usually check each channel/profile directly or use sites like SocialBlade for live totals. It’s kind of fun to watch the number creep up during a big new video or a trending topic, honestly.

I still get a little giddy telling people about these — Hank Green has two novels out and they come as a pair that really stuck with a lot of readers. The first is 'An Absolutely Remarkable Thing', published on September 25, 2018. It follows April May and the surreal, viral-phenomenon mystery that springs up around her discovery of giant statues, and it reads equal parts social satire and sincere character work. It landed with a lot of buzz, and I remember seeing it on bookstore displays and on bus-stop ads — it felt like a book that belonged to the internet age, which is fitting. The follow-up novel is 'A Beautifully Foolish Endeavor', released on July 7, 2020. It continues the story from the first book and pushes deeper into questions about technology, community, and what it means to be human when systems begin to feel almost alive. Both novels were published by Dutton and are written in that energetic, modern voice that mixes humor and earnestness. If you liked one, the other is a must-read; if you haven’t tried them yet, they’re a compact, thoughtful two-book arc that stuck with me long after I closed the covers.

I still get a little giddy when I spot a new episode with Hank Green in my feed — he’s one of those people who pops up more often than you’d expect, but mostly on shows he actually runs. If you want podcasts that regularly feature him (as host, co-host, or main voice), start with 'Dear Hank & John' — that’s the weekly show he does with John Green where they read questions, riff, and sometimes bring in guests or interview people related to their topics. Another steady place is 'The Anthropocene Reviewed', which is Hank’s more personal, essay-style podcast; while it isn’t an interview show in the traditional sense, episodes sometimes include conversations or guest contributions tied to the subject matter. Beyond those two, Hank is a frequent voice on science-adjacent podcasting projects from the SciShow family. 'SciShow Tangents' is the closest fit: it’s casual, conversational, and Hank shows up regularly to discuss odd science topics and occasionally speak with guest experts. The broader 'SciShow' network also releases podcast-format episodes where Hank’s involvement can be recurring, depending on the series. If you’re hunting for guest appearances rather than his own programs, those are more sporadic — he pops onto other people’s shows from time to time. My advice: follow his social feed or subscribe to his channels so you’re alerted when he’s a guest, and use podcast search engines like Listen Notes or Podchaser to filter by his name. I usually queue things up on long train rides and discover half my new favorites that way.

There’s this energized, slightly nerdy thrill I get when I think about how Hank Green approaches a novel — and I’ve dug through interviews, podcasts, and his YouTube chats enough to see a pattern that really clicked for me. He balances planning and discovery: he doesn’t wing everything, but he also leaves room for surprises from his characters. He’ll map out acts and key beats first so the story has a shape, then write scenes to see how the characters actually behave inside that shape. That combination keeps momentum without strangling creativity. He talks a lot about discipline too — setting daily targets or at least regular writing habits so the manuscript keeps moving forward, then switching gears into ruthless revision once a full draft exists. From what he’s described, the early drafts are about finding voice and stakes; later drafts are precise, shaving away anything that doesn’t serve the engine of the plot. He leans on feedback often: friends, beta readers, and professional editors help point out where jokes land or where the science and internet-culture bits need tightening. As a reader who loved 'An Absolutely Remarkable Thing' and 'A Beautifully Foolish Endeavor', I appreciate this hybrid approach. It explains why his books feel structured and fast-paced but still full of character discovery. If you’re trying to write, his method suggests being kind to early messes, planning enough to avoid getting lost, and inviting outside eyes to make the work cleaner and braver.

I get excited every time someone asks about Hank Green's novels getting the movie treatment — those books feel so cinematic to me. Right now, though, there's no confirmed release date for a film adaptation of 'An Absolutely Remarkable Thing' or its sequel 'A Beautifully Foolish Endeavor'. From what I've tracked in fan communities and Hank's own social feed over time, there have been whispers about interest from the industry, but nothing that amounts to a publicly announced, scheduled production with a studio, director, and release window. If a project does get picked up, the timeline can be annoyingly slow. First someone options the rights, then a script gets written (and rewritten), talent gets attached, and a studio decides whether to greenlight production. That whole chain can take a few years even for a fast-moving property — and it can take a decade if things stall. Given how layered and topical those books are, I personally think they'd either make a tight feature film that trims some arcs, or — my hope — a limited series that preserves the satire and character development. For now, I keep an eye on Hank's posts, the publisher's announcements, and trades like Variety for the first signs. If you want the same, follow his socials and sign up for the publisher newsletter; those are the earliest places news usually drops, and it’s fun to watch the speculation build while sipping tea and re-reading favorite passages.

I get way too excited about book lists, so here’s a Hank-Green-flavored reading roadmap for sci-fi fans—compiled from things he’s talked about over the years and the vibe he usually recommends: smart, curious, and with a strong dose of wonder. Start with accessible, idea-driven stories: 'The Martian' by Andy Weir (pure fun, engineering-forward survival), 'Contact' by Carl Sagan (big-idea first contact with real science heart), and 'The Three-Body Problem' by Cixin Liu (cosmic scale, strange concepts). These show the range from personal grit to mind-bending cosmology. Mix in classics that shape the genre: 'Dune' by Frank Herbert for politics and ecology, 'Neuromancer' by William Gibson for the cyberpunk mood, and 'The Left Hand of Darkness' by Ursula K. Le Guin for sociological speculation. For emotional heft and war-as-science-fiction, read 'The Forever War' by Joe Haldeman. For modern weirdness, toss in 'Annihilation' by Jeff VanderMeer to taste the uncanny. If you want space-opera momentum, try 'Leviathan Wakes' by James S.A. Corey (start of 'The Expanse') or the sprawling 'Hyperion' by Dan Simmons. Sprinkle in novellas/shorts like 'Binti' by Nnedi Okorafor and 'All Systems Red' by Martha Wells for quick, brilliant hits. If you’re following Hank’s approach, pair fiction with nonfiction curiosity boosts: 'A Brief History of Time' or something lighter like 'Astrophysics for People in a Hurry' to appreciate the real science. Read in waves—classics, then modern hard sci-fi, then speculative fiction—and you’ll get why Hank roots for books that make you think and care. If you want, I can sort these into a 6-month reading plan that balances length and variety.

Man, Dan Greene's path is actually a weirdly inspiring one if you dig into the old interviews and forum posts. He didn't just pop out of the gate fully formed, which I find kind of reassuring. I remember reading this long-deleted blog post where he talked about writing terrible fanfiction for obscure RPGs and posting it on Geocities-style sites, just for the fun of it. No audience, no plan, just pure, cringeworthy practice. He had some office job that bored him senseless and he'd scribble during lunch breaks. The pivot point seems to have been getting involved in a specific online serialized fiction community in the early 2010s. He started posting chapters for what would eventually become 'The Last Iron Tower' on a site that's since shut down. The feedback loop there was brutal but honest; you either improved fast or got ignored. He credits that anonymous, nitpicky reader base with hammering out his early bad habits. His first official 'debut' was basically that serial getting cleaned up and self-published on Amazon KDP after a few years of that grind. It's a very modern, internet-forged origin story.
