MediaFLO USA beefed up its news programming slate over the weekend with the addition of three new permanent 24/7 cable news channels: CNBC, MSNBC and Fox News. NBC Universal’s NBC News2Go channel, which pulled content from the network’s various news properties, has been replaced by the two NBC news channels in the programming guide. By Sunday evening, MediaFLO’s temporary NBC Olympics mobile channel, which was exclusive to AT&T (NYSE: T), was no longer in the lineup and the news channels began cropping up. The new channels are available on Verizon (NYSE: VZ) and AT&T and come just in time for the US political party conventions. (Release).
