The combination of Hulu + Live TV and Fubo brings together 6.2 million streaming subscribers in North America, with roughly $6 billion in sales. Its biggest rival, Google’s YouTube, had more than 8 million subscribers last year when it last publicized those numbers.

In a surprising deal announced on Monday, Disney is set to combine its Hulu Live TV business with Fubo, the live TV streaming service known for its extensive sports coverage. Under the terms of the deal, Disney will own about 70% of Fubo, which will continue to be available to viewers as a separate offering.
