Not that anyone will really care, but for an article in my school newspaper, I was determined to find out what the students' favorite shows were. I surveyed over 200 students and found:

Comedy:
Friends, with 28%
The Simpsons, with 24%
Will & Grace, with 14%
Everybody Loves Raymond, with 6%
The Drew Carrey Show, with 6%

Drama:
ER, with 26%
Gilmore Girls, with 14%
CSI, with 14%
Law and Order, with 11%
Six Feet Under, with 5%
