Disney said the acquisition would help "increase its international footprint" and "expand its direct-to-consumer offerings," which includes ESPN+, plus its much-anticipated video streaming service Disney+, set to launch in late 2019.

"This is an extraordinary and historic moment for us—one that will create significant long-term value for our company and our shareholders," The Walt Disney Company's CEO Bob Iger, said in a statement online.

"Combining Disney’s and 21st Century Fox's wealth of creative content and proven talent creates the preeminent global entertainment company, well positioned to lead in an incredibly dynamic and transformative era."

The merger hasn't only put question marks on the future of its content, but also on jobs at the merged company.

As per The Hollywood Reporter, 4,000 layoffs are expected as Disney promises $2 billion in cost savings, with cuts to be felt in roles that are overlap between the two companies, such as marketing, distribution, and home entertainment.
