Video Add-ons: More English channel add-ons

I am still new to the Pi Zero and OSMC so correct me if I am missing something that is already fixed but looking for some channels in English that you have on the OS. Two channels I notice right off the bat are Nickelodeon and Disney. Will they be added in the future?

I think you misunderstood the concept of OSMC. OSMC will not provide any content or “channels”.
Kodi which is the mediacenter part of OSMC supports (legal) addons that can provide certain content (e.g. via youtube addon).
