"I think the opportunity for innovation is just massive (with mobile)," Jason Robins, CEO of DraftKings, told ESPN. "Not to say that you can't innovate on the retail side, but it's quite literally a limited space. Mobile, you can do anything with. There is no limit to where I think this is going to go, with integrations of streaming ... I think eventually it integrates with voice assistance in the home, smart TVs. The opportunities really are endless as technology advances."
