Spider-Man in film dates back to 1977, the rights belonging to Marvel until 1999, when Sony bought them for $7 million. He has been Marvel's most successful character in the cinema industry ever since. After selling the Spider-Man motion picture rights to Sony, Marvel eventually founded its own studio, developing the Marvel Cinematic Universe (MCU) based on the characters they still held the rights to. This would change in 2016, when Sony and Disney entered an agreement to include Spider-Man in the MCU. Despite some disagreements pertaining to finances and merchandising between the two parties, the agreement proved a successful endeavor for both companies. The following two Avengers sequels, finally with Spider-Man, crossed the $2 billion mark at worldwide box office for the first time. Meanwhile, Sony in association with Marvel launched the Sony's Spider-Man Universe (SSU), with Sony entering a 3 billion-dollar streaming agreement with Netflix and Disney.

Marvel Entertainment, LLC was an American entertainment company founded in June 1998 and based in New York City, formed by the merger of Marvel Entertainment Group and Toy Biz. The company has been a wholly owned subsidiary of The Walt Disney Company since 2009, and was mainly known for consumer products, licensing, and comic books by Marvel Comics, as well as its early forays into films and television/streaming shows, including those within the Marvel Cinematic Universe (MCU).
