CBS has announced its fall premiere dates for the 2009-10 season and, because this is CBS we're talking about, it's the most orderly of any announced schedule to date.

All but two of CBS' shows -- returning and new -- will premiere between Monday, Sept. 21 and Sunday, Sept. 27. And -- wouldn't you know it? -- CBS' premiere dates coincide with the official start of the Nielsen season.

The two exceptions are "Survivor: Samoa" and "Three Rivers." The long-running reality hit's 19th installment will premiere on Thursday, Sept. 17, one week ahead of the Thursday premieres for "CSI: Crime Scene Investigation" and "The Mentalist." The organ transplant drama "Three Rivers," featuring the return of "Moonlight" star Alex O'Loughlin, will premiere on Sunday, Oct. 4, allowing the 15th installment of "The Amazing Race" to have two-hour launch on Sunday, Sept. 27.

Because CBS is proud of the longevity of much of its schedule (including "60 Minutes" starting its 42nd season), it included original premiere dates for all shows in the network press release.
