Oprah's interview with Meghan and Harry drew a staggering 17 million viewers
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.
The high ratings are a testament to the public's curiosity about the royal couple; confidence in Winfrey as an interviewer; and the enduring power of the broadcast TV platform.
While TV ratings continue to erode year after year as people choose from an ever-growing buffet of entertainment options, legacy networks still have the ability to convene large numbers of people, whether for breaking news events, sports, or well-publicized specials like the Harry and Meghan interview.
The Super Bowl is in a league of its own, ratings wise, with almost 100 million viewers. CBS debuted a new drama, "The Equalizer," after this year's Super Bowl, and netted about 22 million viewers.
Other than "The Equalizer," the Winfrey interview is "the biggest audience for any non-sports program on the broadcast networks this season," according to The Hollywood Reporter.
The Nielsen ratings do not take some forms of online streaming into account. While CBS did not release exact numbers, the network said "this was CBS' most-live-streamed event outside of the NFL and Super Bowl Sunday this season."
Twitter was practically aflame with reactions during both the East and West Coast airings of the special on Sunday.
There was near-unanimous praise for Winfrey's interviewing prowess. "Oprah is still the queen of the TV interview," Baltimore Sun media critic David Zurawik wrote immediately afterward.
At the end of the broadcast, Meghan said her family -- having relocated to California and stepped back from official royal life -- isn't just surviving now, but thriving.
"In some ways, this is just the beginning for us," she said.
And it's just the beginning of the fallout too.
