How Systems Work

If You're Not Paying, You're the Product

Ages 10–14 25 min read Intermediate

Instagram is free. TikTok is free. YouTube is free. Google is free. But these companies are worth hundreds of billions of dollars. If you're not paying them, who is? And what are they buying?

The answer: advertisers are paying, and they're buying your attention.

The Attention Economy

In the industrial economy, the scarce resource was raw materials. In the information economy, information is abundant — what's scarce is human attention. Companies that capture your attention can sell it to advertisers.

This creates a simple equation:

  • More time you spend on the app = more ads you see = more money the company makes

Every design decision — the layout, the colours, the algorithm, the notifications — is optimised for one metric: time on platform.

The Numbers

  • Meta (Facebook/Instagram): Revenue of US$117 billion in 2023 — almost entirely from advertising. That's approximately $36 per user per year. Your attention is worth $36 to Facebook.
  • Google: Revenue of US$307 billion — ~80% from advertising.
  • TikTok: Estimated US$120 billion valuation, ad-funded.

Australian digital advertising spending reached $14.7 billion in 2023 (IAB Australia) — more than TV, radio, and print combined.

What They're Actually Selling

Companies don't just sell "ads." They sell targeted access to you. Because these platforms track everything you do — what you click, how long you look, what you search, where you go — they can tell advertisers:

  • "This user is a 14-year-old in Melbourne interested in skateboarding, music, and fast food"
  • "Show them ads for Vans shoes, Spotify Premium, and McDonald's"

The product isn't the ad. The product is you — your profile, your habits, your attention, your data.

Why It Matters

When a company's profit depends on keeping you scrolling, their interests and your interests diverge. You want to spend your time well. They want to spend your time profitably. These are not the same thing.

Tonight's Question

"If your attention is worth $36/year to Facebook, what is it worth to YOU? How would you rather spend those hours?"

Calculate Your Attention Cost

  1. Check screen time data on each family member's phone.
  2. For each social media app, calculate: hours per week × 52 = hours per year.
  3. If you earn (or could earn) $20/hour, what is that time worth?
  4. Compare: your time value vs what the company earns from your attention ($36/year on Facebook).
  5. Discuss: who's getting the better deal — you or the platform?

Go Further

  • Documentary: The Social Dilemma (2020) — tech insiders explain the attention economy.
  • Book: The Age of Surveillance Capitalism by Shoshana Zuboff (2019) — how tech companies monetise human behaviour.
  • Research: How does targeted advertising work? What data do platforms collect about you?
  • Question: Should social media be regulated like tobacco or gambling, given its addictive design?

What We Simplified

  • Free services have real value. Google Maps, Wikipedia, and communication tools genuinely improve lives. "Free" doesn't automatically mean exploitative.
  • Not all screen time is equal. Watching an educational documentary is different from mindlessly scrolling. The quality of attention matters, not just the quantity.
  • The $36/user is a global average. Australian users are worth more to advertisers than users in developing countries.
