Ninty has confirmed that 9.8 million people have subscribed to Switch Online, following the service's launch in September last year.
The premium online service gives members access to a bunch of extra content, including online multiplayer gaming, classic NES titles, and cloud saves. The near-10 million figure includes the family membership option, but it doesn't factor in free trial accounts.
Former Nintendo of America boss Reggie Fils-Aime said last year that Switch Online is the true successor to the Virtual Console.
Switch Online's NES lineup includes a number of the system's biggest titles, including Donkey Kong, Metroid, Super Mario Bros., Super Mario Bros. The Lost Levels, Super Mario Bros. 3, The Legend of Zelda, and more.
