While Zelda has been around since 1987, NPD's tracked sales only begin in 1995. The total for the franchise from 1995 to the present comes in at $1.4 billion, and interestingly Naji pointed out, "Zelda is the top-selling property of all time within the Adventure super genre, selling 54 percent more revenue than the next best-selling franchise, Resident Evil."
Breath of the Wild sold over 900,000 physical units, bumping the Zelda franchise total even higher, and NPD noted that "Switch's packaged software sold 1.3m units, a record high for a Nintendo platform launch." Even 1-2 Switch made the top 20 best-selling games chart (see below) with an attach rate of 19 percent.
