An estimated 22.3 million watched oppressed swimsuit model Jenna Morasca win Survivor Sunday night, helping CBS score another weekly ratings win. CSI was the top-ranked show with 25.1 million viewers, followed by American Idol's Tuesday edition, Survivor, American Idol (Wed.) and ER. Fox's Beverly Hills, 90210 reunion, meanwhile, showed little zip, placing 70th with 7 million viewers. I blame Tori.
