343 Industries Reveals Halo's Impressive $6 Billion Revenue from Games and Multimedia.

The Halo franchise has generated multiple billions of dollars in revenues across games and other media, according to 343 Industries creative director Frank O'Connor. The franchise has sold over 81 million copies as of February 2021, and has earned $6 billion from sales of transmedia content including books, comics, and spin-off series like Halo Legends and the controversial Halo TV show. The Bungie-era games did not have live monetization outside of map packs and extra additions, whereas microtransactions were introduced with Halo 5's REQ system and subsequently in Halo Infinite's direct cosmetic purchases.
