(Reuters) - Walt Disney Co is actively pursuing the purchase of WarnerMedia’s nearly 10 percent stake in Hulu, entertainment business news portal Variety reported on Wednesday, citing sources.

Disney, Comcast and Twenty-First Century Fox Inc each had a 30 percent stake in the video streaming service Hulu, as of September 2018.

Time Warner, renamed WarnerMedia after its acquisition by telecom company AT&T Inc, holds a 10 percent passive stake in Hulu.

In November last year, AT&T committed to cutting its heavy debt load in 2019 through a variety of measures, including a review of all of its non-core assets such as its stake in Hulu for a possible sale.

Disney, Hulu and AT&T did not immediately respond to Reuters’ request for comment.
