I am wondering what the times like 9/8c mean. I thought the program lasts from 8 to 9, but that turns out not accurate. Sorry for my ignorance, but I don't live in the US. Can someone explain?
Almost, but not quite. The main part of the United States (except for Alaska and Hawaii) is divided into 4 time zones. From the Atlantic to the Pacific, they are Eastern, Central, Mountain, and Pacific. When an announcer or advertisement says 8/9C, it usually means 8:00 Eastern time zone and 9:00 Central.

Thank you very much Dynamo1. But what about the other time zones then? I always thought they aired it at the same time, and that time zones that were behind just get to see it an hour later (or how much they lie behind).
If a show is taped or filmed, like the CSI series, they usually air first in the Eastern and Central time zones. For example, CSI Miami will air at 10:00 Eastern, 9:00 Central. Then it will air 9:00 Mountain, and again at 10:00 Pacific. If something is aired live, it could be like 10E, 9C, 8M, 7P.
