Discovery HD taking a step backwards: Non-HD commercals

Has anyone noticed something a bit different about the makeup of Discovery HD Theater? It used to be that they only had HD content and nothing less. Then all of a sudden they started showing Bose commercials that were not HD. I thought to myself, "OK, this is just Bose's marketing team at it again and trying to reach a high income market. That's OK." But then again today I noticed that there was more then just Bose. Delta airlines has a non-HD commercial now too.

Is Discovery HD Theater going to drop the "Theater" part? Currently they don't run any commercials throughout the entire main program then run one or two commercials, usually for themselves or Circuit City,
then a "Short Topic" for about 10 minutes. Does the increase in the amount of non-HD ads indicate that they are going to start putting the normal commercial breaks into these programs?
