Or watching live. Tend to PVR all commercial channel programs I want to watch and save upto a quarter of each hour in skipping the ads.
That is what was getting at. I find that sometimes there is nearer 20 minutes of ads and trailers per hour.
On top of that, many shows also do "
Coming up..." to try to persuade viewers to stick around, and "
What you saw before the ads..." to capture viewers arriving from other channels mid-broadcast.
Often, an hour long show can be cut down to around 30 minutes.
My sister takes this a bit too far and fast forwards through the '
boring bits' as well so that hour becomes a rushed 15 minutes!
