For decades, the formula for launching a blockbuster was relatively straightforward: spend heavily on production, then spend heavily again making sure everyone knows the movie exists. That formula is beginning to look much less reliable.
The contrast between Supergirl and Iron Lung offers a particularly striking example.
Supergirl reportedly cost around $170 million to produce, backed by the distribution power of Warner Bros. and DC Studios and a marketing budget reportedly exceeding $115 million.
Iron Lung, meanwhile, came from YouTube creator Mark Fischbach, better known as Markiplier. Based on David Szymanski’s independent video game, the movie reportedly cost just $3 million to make and relied largely on the audience Fischbach had already built online.
Fan demand helped push the independent film onto more than 4,000 screens, and it eventually generated more than $50 million worldwide.
The lesson is bigger than one successful indie film.
Fandom is increasingly becoming its own distribution and marketing infrastructure.
Social Is Where Entertainment Discovery Happens
For younger audiences especially, social platforms are no longer simply where entertainment gets promoted. They are where entertainment gets discovered, discussed and culturally validated.
Deloitte’s 2025 Digital Media Trends report found that 56% of Gen Z consumers and 43% of millennials consider social media content more relevant to them than traditional TV content. Another Deloitte study found that 35% of consumers across generations spend more time watching social video than streaming services.
YouTube alone now competes for attention at a scale that would once have been difficult to imagine for a platform built around creator video.
And discovery increasingly happens through individual moments rather than traditional movie trailers.
A scene becomes a TikTok edit. A character becomes a meme. An interview becomes a reaction video. Fans create theories, recut scenes, debate casting decisions and distribute clips across communities that studios themselves could never manufacture through paid media alone.
Research from Hub Entertainment suggests that 63% of viewers under 36 say clips encountered on social platforms play an important role in deciding what they watch.
That changes the function of entertainment marketing. The trailer is no longer necessarily the beginning of the campaign. Sometimes the audience is.
Fandom Cannot Simply Be Bought
None of this means movie studios should stop advertising. It means paid reach and cultural momentum are not the same thing.
A $100 million campaign can guarantee visibility. It cannot guarantee that people will care enough to talk about what they saw afterward.
Creators such as Markiplier begin from almost the opposite position.
They may lack the distribution infrastructure of a major studio, but they already possess something studios routinely spend enormous amounts trying to manufacture: an audience with an existing emotional investment in the person or property behind the project.
That relationship changes the economics of attention.
Every post does not need to introduce the creator from scratch. Every clip does not need to convince viewers that the project deserves attention. Fans are already waiting for something to participate in.
The strongest entertainment communities then amplify that participation themselves. That is difficult to reproduce through media buying.
Studios Need To Treat Their IP Like Content Engines
The implications extend far beyond movie launches.
Entertainment companies sit on enormous libraries of footage, interviews, deleted scenes, behind-the-scenes material and decades of recognizable intellectual property. Historically, much of that material remained dormant once the promotional cycle around a movie or television show ended.
Social changes the equation.
A 15-year-old scene can suddenly become culturally relevant again because of a meme, celebrity moment or TikTok trend. A forgotten interview can become a vertical video. A piece of archival footage can introduce an old franchise to an entirely new generation.
The opportunity is therefore not simply to produce more advertisements. It is to build systems capable of turning entertainment archives into always-on social programming.
Companies including Banijay, the production group behind franchises such as Big Brother, Black Mirror and Survivor, are already experimenting with AI-powered content management technology capable of indexing large footage libraries and helping creative teams rapidly surface relevant clips.
For social teams, that could dramatically shorten the distance between an idea and a published piece of content.
Instead of manually searching through hours of footage, teams can increasingly search archives based on characters, objects, dialogue, emotions or situations and quickly turn those moments into new edits.
AI matters here not because it replaces creative judgment, but because it makes enormous media libraries usable at social speed.
The Archive Is Becoming A Strategic Asset
Other platforms are attacking the same opportunity from different angles.
Letterboxd has demonstrated how valuable passionate movie communities can become when discovery, conversation and identity exist in the same environment. The company has also explored ways to make harder-to-find films available directly to its community, potentially giving older or niche titles new commercial lives.
Analytics companies such as Tubular, meanwhile, help media companies understand which content, creators and formats are actually generating attention across social platforms.
Together, these technologies point toward a different entertainment marketing stack.
Studios will increasingly need systems that can identify what audiences are talking about, locate relevant assets inside massive content libraries, rapidly create platform-native edits and measure how those moments move through culture.
The competitive advantage will not simply belong to whoever owns the most IP. It will belong to whoever can make that IP participate in culture the fastest.
Entertainment Marketing Is Becoming Community Marketing
The biggest shift may ultimately be philosophical. Traditional entertainment marketing was built around interruption.
Buy the billboard. Run the television spot. Own the homepage. Place the trailer before the audience.
Social fandom works differently. It relies on participation.
The audience quotes the scene. Remixes it. Debates it. Shares it. Turns characters into memes. Pulls screenshots into group chats. Builds communities around the smallest details.
Studios cannot control all of those behaviors, nor should they try. Their job increasingly becomes giving audiences more material with which to participate.
That requires a different rhythm from traditional campaign marketing. Instead of concentrating attention around a few major promotional moments, entertainment brands need a continuous flow of culturally relevant material designed for the environments where fandom actually lives.
And increasingly, those environments are TikTok, YouTube, Instagram, Reddit and countless smaller online communities.
The success of Iron Lung does not prove that every creator-led movie will outperform a Hollywood blockbuster. But it does highlight something much more important.
Attention can be bought. Fandom has to be built.
As entertainment becomes increasingly shaped by social discovery, the companies that understand that distinction may find themselves with an advantage no blockbuster-sized marketing budget can guarantee.
