You'll only need to have the latest version of the Hulu app to see the changes.

This is arguably overdue. Hulu's live TV has been available on other platforms for a long time, including most other media players, some smart TVs, desktops and consoles. Android TV isn't the largest platform, but it has a sizeable base thanks in no small part to Sony's support. Those users now don't have to subscribe to another service, use another device or otherwise jump through hoops just to get an internet-only live TV package.
