Back at the beginning, I signed up for a trial. The first thing I did was try some on-demand, and it made me sit through A LOT of commercials before the content started.
Considering that Youtube TV was 4-5x the cost of Netflix and Amazon Prime, and both are commercial-free, I canceled immediately. I watch so little TV that it's cheaper to just buy the shows I want to watch outright on Google Play... Commercial-free.
