Every week, Parrot Analytics provides Business Insider with a list of the nine most in-demand TV shows on streaming services in the US. The data is based on "demand expressions," Parrot Analytics' globally standardized TV-demand measurement unit. Audience demand reflects the desire, engagement, and viewership weighted by importance, so a stream or a download is a higher expression of demand than a "like" or a comment on social media, for instance.
"Narcos: Mexico" is a new addition this week ahead of the second season's debut in February.
