Tim,
Surprisingly, these are the requests I have seen as well. I worked at one of the biggest US networks recently and they had an entire department that was dedicated to creating…..PODCAST GRAPHICS!!
However, I have had my fair share of HD requests as well. But, considering that I upgraded to HD just last year, the requests for small format delivery have increased tremendously. From 0 to in excess of 10 major projects per year.
