Why Is Substack Growing While Traditional Media Keeps Shrinking?

Substack crossed 3 million paid subscriptions in early 2024, up from just 1 million in 2021. Those aren't free newsletter signups – those are people paying money directly to writers they want to read. That's the part that deserves attention.

The Core Shift: From Audiences to Subscribers

For most of media history, the business model worked like this: build an audience, sell their attention to advertisers, use that advertising money to fund journalism and content. Readers were the product, not the customer. The publication stood between the writer and the reader, owning the relationship, the distribution, and the revenue.

Substack flips that structure almost entirely. A writer builds a direct relationship with readers, and readers choose to pay the writer directly – typically $5–$10/month for a paid subscription. Substack takes 10% of subscription revenue, and the writer keeps the rest. There's no algorithm deciding who sees the work, no advertiser to appease, no editor with a mandate to chase traffic. The writer and reader are the two parties in the relationship, and everyone else is out of the picture.

That model sounds simple, but it represents a fundamental realignment of incentives. When your income comes from subscribers rather than advertisers, you write what your readers value – not what generates outrage clicks or satisfies a brand safety requirement. That distinction is more significant than it looks.

Why Traditional Media Is Struggling – The Actual Reasons

The problems in traditional media didn't appear overnight. They've been building since the mid-2000s, and they're structural, not just cyclical. Understanding what's actually going wrong makes it clearer why something like Substack can succeed alongside the carnage.

The advertising model broke. Digital advertising gutted the economics that supported newsrooms. When print was the only way to reach a local audience, local businesses had to advertise with local papers. Then the internet arrived, Google and Facebook took over digital advertising at massive scale and efficiency, and the local paper's primary revenue stream collapsed. National outlets fared somewhat better but still lost enormous share. The paywalls most outlets have erected are a response to this – an attempt to shift to reader revenue – but many built them too late or without enough reader trust to make them work.

Aggregation eroded the relationship with readers. Social media platforms became the dominant way people discovered news, which meant readers increasingly had no relationship with the publication itself – they had a relationship with the feed. If a New York Times story and a BuzzFeed story appeared identically in a Facebook scroll, there was little to distinguish them at the point of discovery. Traffic was plentiful for a while, but loyalty and identity – the things that make readers pay – weren't being built. When Facebook adjusted its algorithm to deprioritize news in 2018, outlets that had built their entire traffic strategy around it lost enormous reach almost overnight.

Trust has been eroding steadily. This one is harder to quantify but impossible to ignore. Polling consistently shows declining trust in media institutions across almost every demographic. Some of that is politically motivated, some is the result of real editorial failures, and some is a broader skepticism of large institutional voices that has become culturally widespread. Whatever the cause, a reader who doesn't fully trust a publication is much harder to convert into a paying subscriber – and a writer people actually trust personally has a meaningful advantage.

What Substack Figured Out (and Why It Works)

Substack didn't invent newsletters. It didn't invent the internet or direct-to-reader publishing. What it did was remove enough friction from the model that writers who had built personal trust with an audience could actually monetize it without building an entire media company.

Before platforms like Substack, a journalist who wanted to go independent needed to set up their own payment processing, manage a subscriber list, build a website, handle email deliverability, and figure out promotion – all while writing. Substack collapsed all of that into a single dashboard. The infrastructure cost went to near-zero, which meant the economics could work even for writers with relatively small audiences. A newsletter with 1,000 paid subscribers at $7/month generates $84,000 a year before Substack's cut. That's a viable living for a solo writer with no staff and minimal overhead.

The other thing Substack understood is that readers increasingly want to follow people, not publications. This shift has been building for years – it's visible in the rise of individual YouTubers over TV channels, individual podcasters over radio networks, individual creators over media brands. People develop trust with a specific voice, a specific perspective, a specific person. Substack is built around that logic. You subscribe to a writer, not a masthead.

The Writers Who Are Thriving – And What That Tells Us

Some of the biggest Substack earners are former journalists from major outlets who brought their readership with them when they left. Writers like Matt Taibbi, Heather Cox Richardson, and Glenn Greenwald built their audiences inside institutions and then migrated them to direct-subscription models. Their success isn't really a Substack story – it's a story about what happens when trust is portable.

But there are also writers who built their entire following on Substack itself, with no prior institutional platform. That's arguably the more interesting phenomenon, because it suggests the model works not just as an exit strategy for established names but as a genuine entry point for new voices. Niche expertise, consistent perspective, and genuine engagement with readers turns out to be enough to build a sustainable subscriber base – even without a masthead behind you.

The niches that perform well on Substack are revealing. Local news has seen a quiet revival through the platform, with independent local reporters funding their work through community subscriptions in places where the local paper has either died or been hollowed out by hedge fund ownership. Finance, technology, politics, culture, and literary writing all have strong communities. What these niches share is that their readers are motivated enough to pay – either because the information is financially valuable, because it's ideologically important to them, or because the writing itself is genuinely pleasurable.

The Criticism Worth Taking Seriously

Substack isn't without problems, and the criticisms leveled at it are worth acknowledging honestly.

The platform has faced significant controversy over its approach to content moderation – or the relative lack of it. In 2024, Substack came under public pressure after it became clear that newsletters spreading misinformation and extremist content were operating on the platform and, in some cases, generating revenue that Substack received a cut of. The company's response – defending editorial independence while acknowledging some limits – satisfied some and frustrated many others.

There's also a legitimate structural concern about concentration. The Substack model works very well for writers with existing large audiences and less well for everyone else. The distribution benefits scale with the audience you already have, which means the platform can inadvertently reinforce existing inequalities in who gets heard and who gets paid. A handful of top writers make the vast majority of the revenue.

And the model is only as stable as the relationship between writer and reader. Publication brands can survive individual writers coming and going – a person's newsletter cannot. If you subscribe to a writer who burns out, moves on, or pivots in a direction you don't follow, the subscription ends with no institutional continuity to fall back on.

What This Means for the Future of Media

The Substack story isn't really about Substack specifically – it's about the broader fragmentation of media into smaller, more direct, more trust-based units. That trend isn't going to reverse. The economics of large institutional media continue to be difficult, and the cultural trust that supported those institutions continues to erode. Meanwhile, the tools for individuals to build and monetize direct relationships with audiences keep getting better and cheaper.

What's emerging looks less like a single media landscape and more like a layered ecosystem. A handful of large institutions still do the expensive, labor-intensive work of investigative journalism and global coverage. Alongside them, thousands of individual writers and small teams serve specific audiences with specific needs and perspectives. The two aren't necessarily in competition – they solve different problems.

The question for the next decade isn't whether newsletters and creator-led media will persist. They will. The question is whether the direct-subscription model can support the kinds of journalism – resource-intensive, politically uncomfortable, long-term investigative work – that requires more than one person and a laptop. So far, the evidence on that is mixed. But the direction of travel is clear enough: readers are voting with their wallets for voices they trust, and the institutions that can't build that trust are going to keep finding it difficult.

FAQ

Is Substack profitable as a company? Substack has not publicly disclosed profitability, but the company has raised significant venture capital and operates on a 10% revenue share from paid subscriptions. As total paid subscription volume grows, the economics improve. The company has been focused on growth over profitability in recent years, which is a typical VC-backed startup posture.

Can anyone make money on Substack? Technically yes, but practically it's harder than it looks. The writers making substantial income on the platform generally fall into two categories: those who brought large existing audiences from institutional roles, and those who spent years consistently building an audience from scratch. There's no shortcut to the trust and readership that converts to paying subscribers.

How does Substack compare to other newsletter platforms? Competitors like Ghost, Beehiiv, and ConvertKit offer similar functionality, often with lower or no revenue share. Ghost in particular is popular with writers who want more control and are willing to handle more of their own setup. Substack's advantage is its built-in discovery features and the network effects of its reader app, which surfaces other newsletters to existing readers.

Is the Substack growth story unique to newsletters? The same underlying dynamic – readers paying directly for content from trusted individual voices – is playing out across podcasts, YouTube, Patreon, and other creator platforms. Substack is one visible example of a much broader structural shift in how media gets made and funded.

Does this mean traditional journalism is dying? Not entirely. Investigative journalism, foreign correspondence, and accountability reporting still largely depend on institutional infrastructure. But the economic models supporting that infrastructure are under serious strain, and the outlets that will survive are likely those that have found ways to build genuine subscriber loyalty rather than relying on advertising or algorithm-driven traffic.
