It's set to launch in April 2020
The new LX news service launched today, first on YouTube, and additionally as a streaming and over-the-air TV network in April 2020.
Oops... Thanks.
There is a limited timing service from NBC called NBC News NOW that airs from 3-11pm EST daily.
You can try adding the link - https://nbcnews2.akamaized.net/hls/live/723426/nbc-news1023105345-ua/master.m3u8
NBC News NOW is already available as ch6758. It is not possible to use a static URL as it changes every day.
The newer 24/7 NBC News channel is not live yet.
Is this channel still working? I've been getting the following error recently, even though NBC News still seems to stream for free on the front page of https://www.nbcnews.com/now
