Why this one won
Netflix competes with every form of entertainment, not just streaming. Hours watched is the honest test of whether a subscriber finds the service worth more than the alternative. It feeds directly into churn, pricing power and content commissioning decisions. Nothing else captures 'do you reach for Netflix when you're bored?'

What they considered and rejected
| Metric | Why it was considered | Outcome |
|---|---|---|
| Subscribers | Snapshot, not engagement | Eliminated |
| Titles watched | Could be short clicks | Eliminated |
| Hours watched | Honest attention | Kept |
Lessons learned
When you compete for attention, measure attention. Hours watched beats subscribers because a churned subscriber still counts in the short term; declining hours predicts the churn.

Weekly active creators sharing videos
Loom's viral wedge is sharing. A video that's recorded but never shared is a private use case with zero network effect. The weekly active creator metric captures both sides - someone recorded something AND they passed it on - and is the single best predictor of team expansion.

Weekly collaborating teams (2+ users on a board)
Miro solo is a whiteboard tool; Miro multiplayer is a team brain. The weekly collaborating team metric forces the product to focus on the use case that justifies the price: real-time and async team work. Solo boards are fine but they don't retain.

Weekly engaged members (post, comment or message)
LinkedIn's business (recruiting, sales nav, ads) depends on members who actually engage with the network. Passive profile viewers don't generate the data that makes the platform valuable. The weekly engaged member metric filters out ghosts and captures the members whose engagement powers the whole business.
