Harry and Meghan's interview with Oprah Winfrey was a cultural earthquake, with upwards of 17 million viewers measured by Nielsen's TV ratings scale.
CBS, citing Nielsen data, said the two-hour special averaged 17.1 million viewers on Sunday night in the United States.
The interview also aired in some other countries on Sunday, and will air in other markets on Monday, so the global reach is even greater.
In the fragmented US television landscape, 17 million viewers is a massive figure. For comparison's sake, CBS averaged 6.5 million viewers in prime time the previous Sunday night. The interview was also higher-rated than the most recent Emmys and Golden Globes award telecasts.
