It specializes in talent representation, marketing and licensing and event management, among other things. “Content is no longer defined solely by the traditional categories on which our businesses were founded,” the company wrote in its S-1 filing. “Television, movies and live events have been joined by others including podcasts, experiences, social media, multiplayer video games and e-sports. Wherever you are in the world and whatever way you define content, Endeavor is likely playing a role.”An IPO has been rumored since Emanuel and Patrick Whitesell merged their talent agency with sports and modelling agency IMG in 2013. Since then, Endeavor has acquired the Ultimate Fighting Championship, professional bull riders, the Frieze Art Fair and marketing agency 160over90.This is breaking news. Please check back for updates.
