Dr. Alex Connock from the University of Oxford delves into the remarkable story of how a small video-sharing website created 20 years ago became a global media giant.

The world’s largest video-sharing platform, YouTube, just celebrated its 20th anniversary. Founded in February 2005 by former PayPal employees Chad Hurley, Steve Chen, and Jawed Karim, YouTube started with a 19-second video of Karim exploring San Diego Zoo. The platform’s initial impact was so minimal that it wasn’t even mentioned in The Guardian’s coverage of TV’s Digital Revolution at the Edinburgh TV Festival that year.

Fast forward to today, and YouTube has evolved into a massive competitor to traditional television. It uploads as much new video every five minutes as BBC Studios produces in an entire year—around 2,400 hours. The platform’s influence is evident in the success of creators like Mr. Beast, who earned $85 million in 2024 from videos ranging from live Call of Duty play-alongs to funding 1,000 free cataract operations.

As a business, YouTube is now worth approximately $455 billion, a spectacular 275 times return on the $1.65 billion Google paid for it in 2006. YouTube’s gross revenue of $36.1 billion in 2024 is comparable to streaming giant Netflix, but without the financial burden of producing shows, since most content is uploaded for free.

YouTube boasts 2.7 billion monthly active users, or 40% of the entire global population outside China, where it is blocked. It is also one of the biggest music streaming sites and the second-largest social network after Facebook. Additionally, it serves as a paid broadcast channel for 100 million subscribers.

The platform has built a vast video library, encompassing everything from the “Baby Shark Dance” to how-to videos on fixing septic tanks, hypothetical shooting wars between nations, and quantum physics. YouTube has taken over global children’s programming to the point where Wired magazine noted that the future of this genre “isn’t television.” However, the platform has also been criticized as a conduit for disinformation by fact-checkers.

Key Innovations Driving YouTube’s Success

How New Creativity is Paid For

Traditional broadcast and print media use either the risk-on, fixed cost of hiring staff producers and writers or the variable but risky approach of one-off commissioning from freelancers. YouTube flipped this risk profile entirely to the creator, not paying upfront and avoiding production headaches like insurance, cash flow, or contracts.

The Revenue Model of Media

YouTube innovated by dividing advertising income with creators via an advertising income split of roughly 50%. This incentivizes creators to study the science of engagement, as it directly impacts their earnings. For instance, Mr. Beast employs a team to optimize the thumbnails for his videos, enhancing viewer engagement and revenue.

Advertising

Alongside parent company Google/Alphabet, YouTube introduced programmatic video advertising in March 2007. This technology digitally auctions ad space around a particular viewer to the highest bidder in real time. For example, when you watch a high-rating Beyoncé video and see a pre-roll ad for Grammarly, the advertiser’s algorithm liked your profile and bid to show you the ad. This ultra-efficient system challenges the broad, demographics-based broadcast TV advertising market.

Who Makes Content

About 50 million people now consider themselves professional creators, many on YouTube. Influencers have used the site to build businesses without mediation from executives in legacy media, driving a major move towards the democratization and globalization of content production. Brazil and Kenya have huge YouTube creator economies, giving global distribution to diverse voices that would have been disintermediated in the 20th-century media ecology.

The Way We Tell Stories

Traditional TV ads and films build to a climax, while YouTube videos, especially YouTube Shorts, prioritize a big emotive hit in the first few seconds for engagement and regular further hits to keep viewers engaged. Mr. Beast’s leaked internal notes describe how to do sequential escalation, moving to more elaborate or extreme details as a video progresses. He reflects, “I spent basically five years of my life studying virality on YouTube.”

Copyright

YouTube introduced Content ID in 2015, allowing creators to algorithmically discover and claim ad revenue from their own content, providing a new income stream for producers. Through digital rights monetization (DRM), owners can take the money instead of suing for copyright infringement.

Video Technicalities

YouTube has been at the forefront of video production innovations, from 360-degree, 4K, VR, and other tech acronyms. Now, YouTube is integrating generative AI into its program-producing suite for creators, with tight integration of Google’s Veo tools. According to CEO Neal Mohan, “billions of people around the world access to AI.” This is another competitive threat to traditional producers, as bedroom creators can now make their own visual effects-heavy fan-fiction episodes of Star Wars.

News

YouTube has become a rabbit hole of disinformation and conspiracy, with a reinforcement-learning algorithm that prioritizes view time but not editorial accuracy. Covid conspiracy fans got to see ‘5G health risk’ or ‘chemtrail’ videos because the algorithm knew they might like them too. Traditional media brands can respond by meeting the audience where the viewers are and putting their content on YouTube. The BBC has 14.7 million YouTube subscribers, and ITV is exploiting its catalogue to put old episodes of Thunderbirds on there. In February 2025, Channel 4 also announced success in reaching young viewers via YouTube, with full episode views up 169% year on year, surpassing 110 million organic views in the UK.
