Tubi is the biggest ad-supported video service in streaming, and was bought by Fox earlier this yea for a hefty $440 millionr. I sat down with Adam Lewinson, the company's chief content officer, this week as part of the virtual NATPE Streaming Plus conference. We covered a lot of ground, talking about all the company's news about big jumps in viewership, new territories and sections, whether they'll ever make original shows, and why ad-supported video is going to be the way most people watch TV in the streaming future.
