In the wake of ABC’s announcement that it would upgrade its app to live-stream local programming in the New York and Philadelphia areas, TBS and TNT plan to offer live 24/7 streaming of their series and sports coverage beginning this summer. The streams will be available via the channels’ websites and soon-to-launch mobile apps called Watch TNT and Watch TBS. The apps will initially be offered for iOS devices, with support for other platforms expected by the end of the year.

The plan was announced during the Upfronts in New York on Wednesday.

“Tablets and smartphones become television sets, bringing new opportunities for us and for advertisers,” said Turner exec Steve Koonin, in a statement.

“To watch the streams, users will have to log in with their account information from their cable or satellite service,” explains Bloomberg. “The channels are making the move as part of an industry shift toward ‘TV everywhere,’ which lets viewers see the same content online that they typically get from their cable box.”

In addition to regular drama and comedy series, the live streaming will include coverage of the NBA on TNT, MLB on TBS, and March Madness via both networks.

In related news, Nielsen is teaming with ABC to expand Online Campaign Ratings (OCR) for mobile apps.

“The OCR solution measures the audience of digital ads (in a fashion that is similar to how Nielsen measures TV),” reports Cynopsis Digital. “This trial run will expand OCR’s reach from computers and tablet browsers to now also include mobile apps, potentially providing a more holistic understanding of how audiences consume video and video ad content across devices. With this deal, ABC will measure audience demos and the reach and frequency of online campaigns across ABC content on the Web and in mobile apps.”
