Oh wow. A new channel? I've yet to see an Indian news channel target an international audience.
I thought he was only referring to the launch of his existing Republic TV in the U.S. and UK for the Indian community, which they announced recently. See here:

For Indian English news channels, Dish Network/Sling TV in the U.S. has NDTV 24x7, India Today, News18 (rebranded CNN News18) and Times Now. But they're only subscribed to by the Indian diaspora, and that too in low numbers since it is overpriced. Many have switched over to other IPTV services.
