@Foxtronix in Ontario I remember there used to be a infomercial only TV channel called SHOPTV where the "programs" were all 30 min infomercials. There was also the shopping channel, which was similar but at least had hosts selling the products instead of playing recorded ads.
I think they were on cable and I haven't seen either of those channels since getting rid of cable years ago.
@Roi_hartmann - Agreed. I find traditional TV to be pretty restrictive over online streaming as you have to align your schedule to that of your favourite programs. Years ago I used to tape my favourite TV programs but setting the schedules on the VCR and making sure I had enough tape was another hassle. DVRs were still pretty expensive and when they became affordable I pretty much already moved over to online streaming video instead of broadcast TV.
@Cole D - I remember there used to be channels that used to sign off during the overnight hours (after playing the national anthem) but I suppose it was more profitable to play reruns and infomercials instead. Even when the channels signed off they still displayed the test pattern so I suppose the equipment was still being used even though no programs were shown.
