Log inLearning Goal: Understand how advertising-based business models create a structural incentive for tech companies to capture and hold your attention at any cost.
You already know that the attention economy exists. You learned in the foundations course that your focus is the product being sold. Now it is time to go deeper — to understand why the system works the way it does, and why individual tech workers, many of whom genuinely care about user wellbeing, cannot fix it from the inside.
The answer is business model.
Most of the platforms you use every day — social media, search engines, news aggregators, video platforms, free games — make money through advertising. And advertising revenue is determined by one metric above all others: engagement. Time on platform. Sessions per day. Clicks per session. Scroll depth. Video completion rate.
Every product decision at an advertising-funded company passes through a single filter: will this increase engagement? Features that increase engagement ship. Features that reduce engagement get cut. It does not matter if a feature improves user wellbeing. If it reduces time on platform, it hurts revenue.
This is not a conspiracy. It is openly described in investor presentations, earnings calls, and product documentation. Meta reported $131 billion in advertising revenue in 2023. Google reported $307 billion. These numbers are directly proportional to how much of your attention these companies capture.
Tristan Harris, who worked as a design ethicist at Google before co-founding the Center for Humane Technology, saw this from the inside. He describes a structural problem: even well-intentioned employees cannot change the fundamental incentive. The business model demands engagement. Everything else is secondary.
This has a profound implication for you personally. The platforms you use are not neutral tools. They are businesses that profit when you spend more time on them. Every design decision, every algorithm tweak, every notification strategy serves that goal. When you pick up your phone and lose an hour, that is not a bug. It is the product working exactly as designed.
Understanding this is not about becoming cynical. It is about becoming clear-eyed. You cannot navigate a system you do not understand.
Exercise: Choose one platform you use daily. Look up its most recent annual revenue from advertising. Then estimate how many minutes per day you spend on it. You are part of that revenue number. Sit with that for a moment. How does knowing this change your perspective?
Key Takeaway: Advertising-based business models create a structural incentive to capture your attention. This is not a conspiracy — it is the openly stated logic of the industry. Understanding the business model is essential to navigating it.
