Tens of millions of people have viewed productions online during lockdown, according to figures reported by organisations including the National Theatre, which says its own streaming figures equate to all three of its spaces being completely filled for 11 years.
Millions have also tuned in to Andrew Lloyd Webber’s musicals and offerings from the Royal Opera House.
Views for the National Theatre at Home YouTube channel, which releases a new production for audiences to watch for free each week, total more than 10 million.
This includes more than six million streams in the UK, two million streams in the USA, 400,000 streams in Australia, more than 300,000 in Canada, and more than 200,000 streams in Russia and Germany, with viewers coming to the channel from more than 160 countries in total.
One Man, Two Guvnors was the most popular stream, which was watched by 217,000 people at once.
The NT said that more than 40% of its channel’s viewers were under 35, 21% used subtitles, and more than 65,000 viewed the audio-described version of Twelfth Night.
Lisa Burger, executive director and joint chief executive, said: "More than 10 million people have now viewed productions as part of National Theatre at Home since we launched at the start of April. While theatres across the world remain closed, we’re pleased that we can continue to bring the best of British theatre directly into people’s homes every Thursday evening.”
The streaming of Andrew Lloyd Webber’s The Phantom of the Opera, meanwhile, was watched by 12.7 million on YouTube channel The Show Must Go On!.
A spokesman said the channel has 1.27 million subscribers and has so far raised more than £541,000 for charities through donations.
The Royal Opera House reports 5.5 million views of shows it has streamed on Friday evenings.
The most popular of these was The Metamorphosis, with one million views - which chief executive Alex Beard described as "astonishing".
Beard said: "During times of adversity we need the arts more than ever to inspire us and speak to the heart of our shared experience.
"It is heartening to see so many people discover and enjoy the transformative power of music and dance through our #OurHouseToYourHouse programme of free live performances, musical masterclasses and cultural highlights."
Cirque du Soleil has also reported 45 million views of its YouTube channel CirqueConnect Hub, which was launched in March to feature performances by the company.
The Royal Shakespeare Company has also reported a "significant increase" in the number of people making use of its online educational materials for young people.
This includes a ’live lesson’ of Macbeth directed by Polly Findlay and featuring Christopher Eccleston, which received more than 23,000 views, as well as more than 160,000 users accessing the RSC’s daily BBC Bitesize Shakespeare lessons for year 10 students.
Jacqui O’Hanlon, director of education at the Royal Shakespeare Company, said: “Every year, RSC Education reaches more than 500,000 young people who experience, first-hand, the extraordinary power of Shakespeare’s language in their school and the local community.
"As children and parents across the UK adjust to their new ‘virtual classrooms’, this gives us a new challenge and opportunity to extend our support and to work with artists from the RSC’s performance history.”
