Their wiki page has some numbers for the last few years. Parks/Resorts (incl. cruises) made $3.3B in 2016; Studio Entertainment made $2.7B; Disney Media Networks (ABC/etc) made $7.8B. So if you put the TV and films together, that's roughly triple their parks & resorts.

(Edit: changing revenue to income.)

Consumer Products: 5,528

Parks/Resorts: 16,974

Media Networks: 23,689

You need to cater to eyeballs so that people keeps buying the merchandise. Disney, together with Coca Cola, are the world leaders of creating a brand that feels like an essential part of your life; and it all depends on keeping the core product relevant.
