Why Apple stopped talking about iPhone units
A hardware company that reports on services is telling you where the moat moved.
The decision
In 2018 Apple stopped reporting how many iPhones, iPads, and Macs it sold each quarter. In the same breath it began breaking out services revenue and, over time, the size of its installed base. Analysts complained. Apple did not care.
The strategic why
Unit sales are a story about this quarter. The installed base is a story about the next decade. Apple wanted investors — and, just as importantly, its own leadership — measured against the second story.
Once the base is the metric, every decision reorganizes around it. Keep devices in use longer. Sell a bundle to the household, not a phone to the individual. Make each device more useful when it sits next to another one.
What it defends against
A hardware-only Apple lives and dies by the upgrade cycle and by whoever ships a better phone. A services Apple lives on the base, which is enormous, loyal, and slow to move. Competitors can win a comparison review. They cannot win back a family’s photos, subscriptions, and shared purchases in one product cycle.
The risk
Services invite regulators in a way hardware never did. The margin structure that makes the model attractive is the same one that draws scrutiny. Apple’s bet is that the ecosystem is sticky enough to survive being forced open at the edges. So far, that bet has held.
