The 2002-03 TV season just ended, so the postmortem can begin, and not just on CSI. USA TODAY's Gary Levin examines the ratings and hits the high and low points.

Winners

•24 (Fox): American Idol helped spark a 36% ratings increase for Kiefer Sutherland's suspense thriller, the largest for any returning show remaining in its time slot.

•Law & Order: Criminal Intent (NBC): The third incarnation of Dick Wolf's cops-and-courts franchise was up 20% in its second year, and easily bested ABC's buzzed-about Alias.

•Smallville (WB): The network's most-watched drama climbed 14% in its second season, helping the network score bigger overall gains than any other.

•CSI: Miami (CBS): TV's top-rated new drama was a slam-dunk for CBS, with nearly 17 million viewers.

•Joe Millionaire (Fox): The latest reality phenomenon, this eight-week series was this season's No. 2 show. Its final hour was more widely seen than the Oscars.

Losers

•The Practice (ABC): David E. Kelley's legal drama lost 22% of its viewers, in part because of a disastrous January move to Mondays. The show will return on Sundays this fall, but without most of its cast.

•Frasier (NBC): The once-durable Cheers spinoff dropped 16% this season and will limp into its final year.

•The West Wing (NBC): Some blame the political climate; others blame The Bachelor. But 22% fewer viewers elected to watch the White House drama, and this fall it loses creator/writer Aaron Sorkin.

•Enterprise (UPN): The latest saga in UPN's Star Trek franchise was off a whopping 32% in its second season.

•That Was Then (ABC)/Girls Club (Fox): Don't remember them? No surprise. These new dramas won the award for quickest death. Both were canceled after two episodes.
