Why spend all your time watching TV for 24 hour news when you can use a live stream to scan and view the last 4 hours worth in one go? This is perhaps best experienced on a laptop or a desktop.
From within a Youtube live stream (I prefer feeds maintained by their respective sources), use the time bar to go back in the stream. Save time by hovering over the time bar to see thumbnails. These can used to scan past the repeating bits and get to the timeline of a quater of the day, rewinde, pause, seek, et al (being able to listen to how details can change even over 4 hours is a cord-cutting bonus feature).
