Most of my career up until the last couple of years has basically been a training ground for me. Actors that came up in the '50s and '60s, they had the theater, and television was in its infancy.
The same issue is happening on a show like Everybody Loves Raymond now, which is in its eighth year and struggling to come up with good stories. It'll be interesting to see how they do. The bottom line is, it starts with the writers and ends with the writers.
