I just find it more convenient to watch the public broadcast on TV. The news of 19 o' clock is just the right moment before dinner, so I just watch that.
Oh but I do the same most of the time. My smart TV allows me to watch internet stuff on it. With the "Auvio" platform of the RTBF, I can watch the news, TV shows, documentaries and almost everything else from the RTBF online and ALSO on my TV, no need to use my computer anymore. Same when watching France24, Euronews, CNN, Fox... It's all on my TV. If you just came to my place when I'm watching CNN you'd think I do have cable when it's not cable but just internet.
