Comcast to add 35 live TV channels to mobile app

Comcast says 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 on the go.

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 only on its website, from a computer, or on mobile devices for special events like last year's London Olympics.

Comcast Corp.'s update, expected in the coming days, comes as TV ratings provider Nielsen plans to incorporate mobile viewing into its TV ratings starting next fall.
