Those are nine-figure, not six-figure.
But for a non-club example of the same error, see the very next line:
> The way Netflix accounts for these six-figure deals is complicated,
It’s a known issue whereby producers and other people in a position of financial power deliberately shape the deal structures to be deceptively appealing in order to basically keep more of the money for themselves. Google “Hollywood accounting” if you’re curious for more details.
The six figures reference may be a reflection of what the person in question is likely to be walking away from the deal with in terms of “money in their own pockets” as opposed to total money made available to them by Netflix for the purpose of making shows.
When I click the link "also in the six-figure-Netflix-deal club" it takes me to an article[1] titled "$100 MILLION CLUB: 7 Hollywood titans that Netflix, HBO, and others have signed 9-figure deals with during the battle for talent". So that second article correctly matches 9-figure with $100M. This tells me that the first article just has a typo, not that there's some sort of 1/1000 conversion factor for salaries. I have a hard time believing in a 1/1000 conversion factor for salaries without some source clearly explaining that.
