Nintendo's sales data from last night shows that Switch is just shy of 80 million units sold so far. That's in less than 4 years on the market! While plenty of games are helping the Switch achieve those sales, Nintendo mentioned Animal Crossing: New Horizons as the biggest catalyst recently. See their statement on how that game is pushing consumers to buy Switch below.
Sell-through for the overall Nintendo Switch family in this third quarter exceeded the strong showing seen in the same period of last fiscal year, bringing sellthrough to the highest level since launch. The release of software titles like Animal Crossing: New Horizons this fiscal year encouraged more new consumers to purchase Nintendo Switch family hardware, and also encouraged more families that already owned the hardware to purchase a second one.
