The wall between second-screen social TV apps and actually-watching-TV apps is coming down. Sky Sports for iPad is the latest example, having been updated with a range of second-screen features.

The app, which has been downloaded more than 500k times according to Sky, already enables subscribers to watch the satellite broadcaster’s sports channels. But now they can get extra content while they watch.

There’s a new Football Match Centre section offering player and team profiles and statistics, as well as a “curated Twitter feed with aggregated football fan commentary”.

“With over half a million downloads since launch, we hope that the addition of a football second screen experience to the iPad app will continue to excite fans, providing an intuitive and innovative way to follow the match included as part of their Sky Sports subscription,” says Sky Sports Digital Media director David Gibbs in a statement.

It’s interesting to see Sky doing this in its own app. The broadcaster invested in second-screen TV startup Zeebox earlier this year, but there’s no news yet on whether features like those in the Sky Sports app will appear in Zeebox’s standalone app too.
