Success: The Witcher was an immediate hit with fans when it debuted on Netflix in December

'Through its first four weeks of release, 76m member households chose to watch this action-packed fantasy,' the streamer continued in the letter.

However, the use of the phrase 'chose to watch,' along with a footnote stipulating a change in how they report their metrics, points to another instance of Netflix being vague about its market performance.

The footnote explains that a 'view' now constitutes a member choosing to watch a piece of content 'for at least 2 minutes -- long enough to indicate the choice was intentional.'

Setting: The show is set in the fictional medieval-inspired landmass known as 'The Continent'

Franchise: As a further testament to the series' success, the letter continued, 'the show’s launch drove up sales of The Witcher books and games around the world'

The letter goes on to state that 'the new metric is about 35% higher on average than the prior metric,' which only counted views of at least 70 percent of a given episode or film on the service, thereby further beefing up Netflix's numbers.

Meaning, that if a viewer decided to watch even just 3-5 minuted of the show before switching to something else, that would still count as a full-on view for The Witcher.

As a further testament to the series' success, the letter continued, 'the show’s launch drove up sales of The Witcher books and games around the world, and spawned a viral musical hit.'
