The first three seasons of HBO's Game of Thrones covered about 1,980 pages of George R. R. Martin's A Song of Ice and Fire book series, with more than 26.5 total hours on screen.
According to new data from The Guardian, however, the show actually spends less time per page than many other recent book-to-TV adaptations.
Game of Thrones spends approximately 0.8 minutes of screen time per page, while Friday Night Lights, based on the book by H.G. Bissinger, spends 9.15 minutes per page. Boardwalk Empire, inspired by Nelson Johnson's history of corruption in Atlantic City, spends 8.77 minutes per page.
Of course, as the latter two books don't have set story lines, the approach is a bit different. At the other end of the spectrum, Dexter, based on Jeff Lindsay's novel Darkly Dreaming Dexter, spends 2.4 minutes per page.
The following chart, created by Statista, shows eight popular TV series and how much screen time their creators devote to source material.
