Viewers are clearly addicted to "Narcos," Netflix's cocaine industry epic.

The easiest way to tell if a Netflix show has been a hit is to see how long it takes the company to announce if another season is coming. And, in the case of "Narcos," the show centering around renowned drug kingpin Pablo Escobar, it's only taken Netflix one week after Season 2's premiere to confirm that Seasons 3 and 4 have been commissioned.

However, with the new seasons will come a new focus with the show's makers moving away from Escobar in order to examine the wider global cocaine business and its impact on modern life.
