CSI has once again surpassed Friends as TV's most popular show. Drawing more than 30 million viewers, CBS's crime drama ranked as last week's No. 1 program and helped the Eye Network win the Nielsen derby for the fourth straight week. NBC, which had the week's No. 2 and No. 3 shows in Friends and ER, finished a narrow second with 12.3 million viewers. Still, the Peacock remained the top destination for adults 18-49. Among freshman series, CSI: Miami fared the best at No. 9.
