Forget reality TV drama; Sweden’s “Great Moose Migration” livestream is captivating millions with nothing but moose trudging through forests and swimming across the Ångerman River.

This 24/7 slow TV phenomenon, which kicked off on April 15 — a week early due to warm spring weather — has fans glued to their screens for its raw, unscripted beauty. Since its debut in 2019, “Den stora älgvandringen” (The Great Moose Migration) on SVT, Sweden’s public television station, has grown from a quirky experiment to a global hit, drawing 9 million viewers in 2024.

“It’s like watching nature’s slowest marathon,” said Ulla Malmgren, 62, who stocks up on coffee to stay awake for the 20-day event. “When a moose appears, it’s pure magic!”

Fans like Malmgren cheer via a 78,000-strong Facebook group, sharing screenshots of moose splashing through the river near Kullberg, 187 miles northwest of Stockholm.

The setup is simple yet epic: 26 remote cameras, seven night cameras, and a drone capture moose following a millennia-old migration path to summer pastures. The production crew operates the cameras remotely from the town of Umea.

“These animals don’t know they’re stars,” said Johan Erhag, SVT’s project manager. “That’s what makes it so authentic.”

The show’s charm lies in its calm—there is no music or narration, just wind, birds, and the occasional moose plodding by. Viewers, including Cait Borjesson, 60, call it “therapy.” She’s watched for 16 hours straight since Tuesday, finding peace in the natural sounds.

“It’s unbelievably relaxing,” she said. “There’s the natural sounds of the birds, the wind, the trees. It gives you a sense that you’re in nature even if you’re not”.

Why the obsession? Annette Hill, a media professor at Jönköping University, says slow TV offers a soothing escape.

“Nothing catastrophic happens, but it’s gripping in its quiet beauty,” she said.

“Everyone is so stressed today with the social media and the way we produce everything we do in our life, and this is the total opposite of that,” Erhag said on the NBC Today show.

The calming effects of the show even benefit the production crew.

“Everyone who works with it goes down in their normal stress,” Erhag added.

“I feel relaxed, but at the same time, I’m like, ‘Oh, there’s a moose. Oh, what if there’s a moose? I can’t go to the toilet!’” said Moose Migration watcher William Garp Liljefors.

The livestream runs until May 4. Viewers in the U.S. can tune in to the livestream via the SVT Play app if they have a VPN subscription.
