Failed Technologies
The Betamax Myth: Why Better Technology Loses
The technology that wins is almost never the best technology in the room.
The Idea
There's a comfortable story we tell about failed tech: it lost because it was inferior. VHS beat Betamax because VHS was better. But Betamax had superior picture quality and a more compact cassette. What it lacked wasn't engineering — it was longer recording time and a cheaper licensing strategy that got more manufacturers on board. This points to something more unsettling than mere market randomness. Economists call it 'path dependence': the idea that early, often arbitrary advantages compound over time until a technology becomes entrenched not by merit but by momentum. Once enough people own VHS players, video rental stores stock VHS, which means new buyers buy VHS players, which means stores stock more VHS. The loop closes. The better product is locked out not by a single bad decision but by a cascade of individually rational ones. What makes this particularly sharp is that it isn't a bug in markets — it's a feature of any networked system. The value of a technology is often less about what it does and more about what everyone else is already using. This means 'good enough and widespread' will beat 'excellent and rare' almost every time. Technologists tend to believe that quality is destiny. History keeps suggesting otherwise. The failures worth studying aren't the obvious ones — the solutions to problems nobody had — but the genuinely excellent ideas that simply arrived in the wrong sequence.
In the World
In the late 1970s, Sony's engineers were confident Betamax would dominate. It launched first, in 1975, and early reviews were enthusiastic. But Sony made a fateful call: they licensed the format selectively, wanting to control quality and protect the brand. JVC took the opposite approach with VHS. They gave the format away to anyone who asked — Panasonic, RCA, Hitachi — building a coalition of manufacturers almost overnight. By 1977, there were far more VHS machines in living rooms, even though most reviewers still rated Betamax as the sharper format. The tipping point came from an unlikely direction: adult film studios, which needed longer recording times for their content, standardised on VHS because it could record for two hours versus Betamax's one. That drove rental store inventory. Rental store inventory drove consumer purchases. By the mid-1980s, Sony was manufacturing VHS players themselves — a quiet admission of defeat from the company that had bet everything on being right. The lesson isn't that quality doesn't matter. It's that quality is only one variable in a system where timing, coalition-building, and early adoption patterns often carry more weight. Sony's engineers were right about the picture. They were wrong about what the picture was.
Why It Matters
Once you see path dependence, you start spotting it everywhere — not just in technology, but in standards, habits, institutions, and careers. The tools most people use aren't necessarily the best ones; they're the ones that accumulated enough early users to make switching feel costly. This reframes the way you might evaluate your own tools and choices. Are you using a particular platform, workflow, or approach because it genuinely serves you — or because you arrived there first and momentum did the rest? It also changes how you think about innovation. The hard problem isn't always building something better; it's understanding that 'better' only converts into 'dominant' under specific conditions — early timing, low switching costs, network effects working in your favour rather than against you. For anyone building, adopting, or evaluating new technology, this is the real question to sit with: not 'is this the best solution?' but 'does this have the conditions to become the standard solution?' Those are very different questions, and confusing them is how excellent things quietly disappear.
A Question to Ponder
What tool, platform, or habit in your own life might you be loyal to not because it's the best option available, but simply because you got there first?
