How Companies Monetise Your Addiction
You are not the customer of most platforms you use daily. You are the product. Your attention is sold. Your behaviour is profiled. Your engagement is engineered.
The 23-Minute Scroll
Priya picked up her phone to check one message. It was 9:47 PM.
She opened WhatsApp, replied, and then noticed a notification from Instagram. One photo. Then a reel. Then another.
At 10:10 PM she put the phone down. She had not planned to scroll for 23 minutes. She had not enjoyed most of it. She felt slightly worse than before she picked up the phone.
This was not an accident. Every element of the experience - the notification timing, the autoplay, the infinite feed, the red badge on the icon - was designed specifically to maximise the number of minutes she spent inside the app.
Each of those 23 minutes was sold.
Your Attention Is the Product
The business model of most free platforms is simple: the longer you stay, the more ads you see, the more revenue they generate.

Every minute you spend on a platform is monetised. You receive the service free. Your time is the price.

When Tristan Harris, a former Google design ethicist, described the attention economy in testimony before the US Senate in 2023, he said: "The product being sold is a diminished version of you."
Time on Platform: The Core Revenue Metric
Every major platform measures and optimises for DAU (Daily Active Users) and time spent. These metrics directly determine advertising rates.
95 Min/Day Average
TikTok users average 95 minutes per day on the platform - the highest of any app. The algorithm that drives this engagement is explicitly optimised for maximum time-on-app, not user satisfaction.
$164B in 2024
Meta generated $164 billion in revenue in 2024, with 98% from advertising. The company employs thousands of engineers whose primary task is increasing the time users spend inside its apps.
Dark Patterns Designed for Engagement
These are not interface accidents. They are deliberate design choices:
Infinite scroll removes the natural stopping point of a page end. There is no bottom. Research by Aza Raskin, who invented infinite scroll, estimates it costs the world 200,000 hours of human attention daily. He has publicly called it a mistake.
Autoplay eliminates the active decision to continue watching. Netflix, YouTube, and TikTok all default to the next video without requiring any input from you.
Notification design uses red badge counts because red triggers an urgency response in the brain. The number is not important - the urgency feeling is the goal.
Variable rewards - the core mechanic of slot machines - are used in feed design. Most content is mediocre. Occasionally there is something great. That unpredictable reward is what makes people keep scrolling.
A/B Testing: Manipulation at Scale
Every element of a major platform has been tested on millions of users to find the version that maximises engagement.
A/B testing means showing version A to half the users and version B to the other half, then measuring which produces more time on app, more clicks, or more posts. The winner is deployed to everyone.
This process runs continuously. At Meta, thousands of A/B tests run simultaneously. The optimisation target is not your wellbeing. It is the metric that drives revenue.
Internal research from Meta (leaked in the Facebook Papers, 2021) showed the company knew its platforms increased anxiety and depression in teenage girls. The engagement data continued to improve. The features remained.

What That Just Showed You
1. Every minute you spend is worth a measurable amount in advertising revenue. The platform does not care if you enjoyed the minute. It cares that you stayed.
2. The design is not neutral. Autoplay, infinite scroll, variable rewards, red badges - each is a specific engineering choice to extend your time on platform. You are not supposed to know this.
3. You can set limits, but the platform will push back. Most platforms make screen time limits deliberately inconvenient to set. They are buried in settings, require multiple confirmations, and are frequently designed to feel like a punishment rather than a feature.
Three Things Worth Doing
1. Check what platforms track about your usage. iPhone: Settings > Screen Time. Android: Settings > Digital Wellbeing. Look at the actual numbers before deciding whether they are acceptable.
2. Turn off autoplay on every platform you use. YouTube, Netflix, TikTok, Instagram, and Spotify all have autoplay settings. Disabling them restores the active decision to continue.
3. Move app icons off your home screen. The friction of searching for an app reduces impulsive opens by 30% on average. You still have access. You just have to decide to use it.
One Question Before You Continue
A platform shows internal research that its product increases depression in teenage users. The product team does not change the feature. What does this tell you about what the platform is actually optimising for?
