It may be November sweeps, but it was just another Monday and Thursday for ratings champs CBS and NBC.

With the No. 1 rated “CSI: Crime Scene Investigation” pulling in 27.9 million viewers last week, CBS once again topped the ratings, as specials like the Country Music Association Awards and the biopic “Master Spy” took a backseat to regulars like “Everybody Loves Raymond” and “Survivor: Thailand.”

“Master Spy,” the story of Robert Hanssen, averaged just 9.7 million viewers (45th place), while the CMAs landed in 10th place overall with 17.6 million viewers, down slightly from last year, according to Nielsen Media Research.

NBC’s Thursday night slate (“Friends,” “ER,” “Will & Grace”) continued to fill up the rest of Nielsen’s Top 10. Overall, CBS led with an average of 14.2 million viewers, while NBC averaged 13.3 million; ABC, 10.5 million; Fox, 7.4 million; the WB, 5 million and UPN, 4.2 million.

For the week of Nov. 4-10, the Top 10 primetime shows, according to the Nielsen, were as follows:

1. “CSI,” CBS, 27.9 million viewers
2. “Friends,” NBC, 27.5 million
3. “ER,” NBC, 24.4 million
4. “Will & Grace,” NBC, 21.4 million
5. “Everybody Loves Raymond,” CBS, 20.4 million
6. “NFL Monday Night Football,” ABC, 19.4 million
7. “Survivor: Thailand,” CBS, 19.1 million
8. “Law & Order,” NBC, 18.4 million
9. “CSI: Miami,” CBS, 17.9 million
10. CMA Awards, CBS, 17.6 million
