AT&T and McKinsey's Disastrous Cellular Forecast
In 1980, AT&T commissioned McKinsey to forecast US cellular subscribers by the year 2000; the estimate missed the actual number by more than 100x, forcing AT&T to later pay $12.6 billion to buy its way back into mobile.
- McKinsey forecasted only 900,000 US cellular subscribers by 2000
- Actual 2000 subscribers were 109 million — over 100x the forecast
- AT&T later paid $12.6 billion for McCaw Cellular to catch up in wireless
“They forecasted 900,000 people would be subscribed to a cellular telephony network in the year 2000.”
“There were 109 million people, not 900,000, 109 million subscribed in the year 2000.”
