The only annoying thing was that they made a 40 minute program last an hour by padding it out with adverts.
I was amazed at how much Top Gear was censored on BBCA though...
I guess you don't know why shows are 45 minutes in the first place then? Having 15 minutes of commercials has been standard for about 25 years. Prior to that, it was 10 minutes per hour (look at the original ST series or even the early years of Moonlighting). In fact, that's not the standard anymore. I think the standard length of an episode of BSG in its last couple of years was 41 minutes. Also, TV shows are no longer 4 acts, they're now 5. So instead of the old way of commercials at the 15, 30, and 45 minute marks (plus between shows) and just making them longer (because people might leave or flip channels), they keep the breaks the same length but now do them at 12, 24, 36, and 48 minutes and just run one show's end credits right into the next's opening.
Another casualty is opening credits/themes. Older shows had openings lasting as long as 90 seconds, then they dropped to 45 seconds, and now they have maybe a 10 second blip with the name of the series, then the opening credits are shown over the actual show. Lots of them also have the end credits running underneath as the show wraps up, especially the 30 minute shows, because they're down to just over 20 minutes!
