Probably not quite, but for news programming, the last time I timed it for the half hour nightly news, there were 13 minutes of commercials. For decades, I got pissed at the commercials always interrupting a movie.
On TV, a movie will take 2 hours to be broadcast. When you go to buy the same exact movie on DVD it's only, say, 87 minutes long. Disgusting.
I recall BBC America being a bit better than that, though. I wish they'd had more episodes of Red Cap. That Tamzin Outhwaite gal was a real looker and I thoroughly enjoyed the shows; less predictable than US programming.
