How does Netflix calculate views?
Netflix divides total hours viewed by the title’s runtime. The result expresses viewing in units of a complete title; it does not count distinct people who watched from beginning to end.
Doing the arithmetic
A two-hour film with 12 million hours watched has six million views by this measure. A one-hour film with the same hours has twelve million. The titles attracted the same total viewing time even though their view counts differ.
Can I compare a weekly chart with a lifetime figure?
Match the period first. A weekly chart describes viewing during that week; a cumulative figure covers a different interval. Also check whether the entry is a film, a season or the whole series before comparing runtimes.
