Apps downloading to the Apple TV by themselves

Hi there,

This morning I turned on my Apple TV to find that several apps had seemingly downloaded by themselves - they were installed despite the fact that I never downloaded them from the App Store. The apps consisted of various channels (Global Go, City Go, CraveTV, etc).

I haven't received any unusual bills to suggest that my account has been hacked, nor has this happened before. Does anyone have an idea of why this might have happened?

Thank you!
