Netflix says The Witcher is set to be its biggest show ever with 76 million viewers so far

Netflix says its fantasy series The Witcher is on track to be its biggest first-season original TV series ever.

The show, which stars Henry Cavill and is based on a cult series of Polish novels, debuted on December 20 and has since been intentionally watched by 76 million customer households, according to the streaming company.

But these statistics cannot be confirmed by an independent organisation and are only supplied by Netflix itself, which has just changed how it measures what constitutes an "intentional view".

In a letter to investors cited by Variety, Netflix uses a Google trends image to boast that The Witcher is more searched much more than Disney Plus show The Mandalorian, Amazon Prime Video's Jack Ryan and Apple TV Plus's The Morning Show.

"As a testament to how our hit content can penetrate the global zeitgeist and influence popular culture, the show's launch drove up sales of The Witcher books and games around the world, and spawned a viral musical hit," Netflix says in the letter.

Netflix's claim about how many times The Witcher was intentionally viewed means that around 46 percent of its customers watched the show, based on its reported 167.1 million subscribers worldwide as of the end of 2019.
