>To determine the composite index value of the availability of content around the world, the
access to Amazon Prime (Saba, 2016), Netflix (Netflix, n.d.), YouTube Premium (YouTube Help,
n.d.), and adult content was assessed for each country. Countries were given one point for
each service that was freely accessible from within each country. Zero points were given if
the respective services were not accessible from the countries at the time of data collection.
The total of the points for each country were divided by four to get an average value. The
average was multiplied by the weight indicator of 0.14 to determine the value of the Content
Availability indicator.

This is so bad actually because the none of the services have a global catalog. US Netflix vs a european one is totally different. Same with Amazon Prime Videos. In a lot of cases you can't even watch their original content on their own service because they already sold the license to local TV channels
