Mark Rober BioSnap a weekly updated Biography.
Mark Rober is everywhere right now and making serious waves as both a science communicator and mainstream entertainer. The headline everyone is talking about is his collaboration with Sesame Street for the Netflix holiday special Elmo and Mark Rober’s Merry Giftmas, which debuts December 8. Rober joins Elmo and the crew to engineer imaginative gifts, belt out three new songs, and deliver a message that creativity and failure are essential parts of learning. He’s credited as an executive producer alongside Sesame Workshop leads, and plenty of parents will recognize the CrunchLabs brand, Rober’s education company that co-produced the show. According to Netflix’s own announcements and Morty’s TV, Sesame Street execs are hailing it as a dream partnership that celebrates playful STEM learning and family connection. Rober told media outlets that teaming up with Elmo is “pretty much a childhood dream come true,” and he hopes kids will see that with enough imagination, anything is possible.
But his media blitz goes far beyond kids TV. November saw the global launch of Mark Rober TV, a FAST (Free Ad-Supported Streaming Television) channel on Samsung TV Plus, now live across the US, Canada, Australia, and major European markets. This marks Rober’s first 24/7 television footprint, with his science experiments and epic engineering challenges curated for living room audiences. Samsung and Influence Weekly put Rober front and center in their creator-driven expansion, and he’s quoted saying this channel is about making science something people want to do, not just have to do.
On Netflix, beyond the new special, you can now binge watch a seven-episode run of Mark Rober’s CrunchLabs, with some of his biggest viral hits—think elephant toothpaste, robot battles, record-breaking egg drops, and more. The episodes trend shorter than the YouTube originals, and CrunchLabs’ branding is out in front, maximizing family discovery. According to Variety, this is just the start: a fresh, original Mark Rober-hosted competition series is on tap for Netflix in 2026, co-produced with Jimmy Kimmel.
On YouTube and children’s media, Rober recently teamed up with Toys and Colors—one of YouTube's powerhouse kid channels—for a series of CrunchLabs educational challenges and playdates with young fans Kaden and Andrea. The videos are climbing views both on his own channel and Toys and Colors, cross-promoted with the kids’ media powerhouse pocket.watch.
As for public appearances, Rober hit the main stage as a keynote speaker at Adobe MAX 2025, sharing limelight with director James Gunn, firmly establishing himself as a go-to authority for creativity and science. His social media remains focused on the new special, with teasers, behind-the-scenes content, and interactions with notables in both entertainment and STEM education.
To recap the biggest current headline: Mark Rober’s Merry Giftmas with Sesame Street dropping on Netflix December 8, global expansion of his branded channel through Samsung TV Plus, a new Netflix show for 2026, and countless viral-friendly science collabs keeping him squarely in the news cycle. No speculation here—this is a hands-on, influential moment for STEM education and digital-first media.
