London CNN Business  — 

Queen Elizabeth II is celebrating 70 years on the throne this weekend with a busy schedule of ceremonies, parades and parties.

As Britain enjoys a bumper four-day holiday weekend, royal watchers in the United States can tune in for the festivities.

Big Royal occasions often garner huge TV audiences around the world. A staggering 29 million Americans watched Meghan Markle marry Prince Harry in 2018, and 17 million caught their bombshell interview with Oprah last year. Both are expected to attend some of this week’s events.

This is how and when to watch the Platinum Jubilee.

Where to watch

Coverage from the BBC, Britain’s public service broadcaster, will air exclusively on ABC News. “Good Morning America” will follow much of the action across the four days.

“Good Morning America” and “GMA3: What You Need To Know” will broadcast special shows live from London from Thursday.

Other shows and channels, including “Nightline” and ABC News Live, will also cover the events.

“Platinum Party at The Palace” — a two-hour concert with performances by stars, including Diana Ross and Alicia Keys — will air on Saturday, but will be uploaded to Hulu the next day.

CNN’s news coverage on Thursday will be anchored by Royal Correspondent Max Foster from outside Buckingham Palace. He will be joined by CNN’s London-based correspondent Bianca Nobilo and Emily Nash, Hello magazine’s royal editor.
