PHILADELPHIA — Comcast said Tuesday that it is updating its mobile viewing app, Xfinity TV Go, to allow subscribers to watch popular channels, such as CNN, Fox News, Disney Channel, CNBC, ESPN and FX.

Subscribers will be able to watch 35 live TV channels on their Apple and Android devices outside their homes, as long as they have a Wi-Fi connection.

Previously, the nation’s largest cable operator allowed subscribers to watch live feeds only on its website from a computer or on mobile devices for special events.
