Eye’s new immunity challenges

Skein's durability gets big test next season

Ratings for the “Survivor 2” finale may have come up well short of those for its inaugural season, but CBS still has plenty to be happy about with the second run. Now, the question is: How much longer can the “Survivor” torch stay lit?

The concept’s durability will get a major test next season. Instead of spacing out the franchise, the Eye plans to run two installments during the 2001-02 TV year. The first will launch in October; the second’s expected in spring 2002.

With so much “Survivor” in such a short time, there’s a chance the franchise will lose its status as an event.

For now, however, CBS is basking in the glow of the May 3 “S2” seg. According to Nielsen, the two-hour finale averaged 36.3 million viewers and a 15.9 rating/34 share in the key demo of adults 18-49. While that’s down 30% vs. the first edition of the reality adventure series, CBS still dominated the night by more than doubling the audience of longtime Thursday champ NBC (33.8 million viewers to 16.8 million).
