'The Big Bang Theory,' 'Hawaii Five-0' and more CBS fall premieres

CBS has set premiere dates for its fall shows, and as the network usually does, it will unveil nearly all of its schedule in the first official week of the season.

All of the big four networks are loading up in premiere week (The CW is starting a little earlier), which means that all 20 new series on ABC, CBS, FOX or NBC will have to fight it out against each other and against returning shows. It could get bloody fast.

CBS will have one early starter: "Survivor: Nicaragua" will premiere Sept. 15 in the show's new 8 p.m. Wednesday home. The bulk of the network's schedule, including five new shows and a new Thursday timeslot for "The Big Bang Theory," will debut the week of Sept. 20. "The Amazing Race" will have a 90-minute premiere on Sunday, Sept. 26, and "CSI: Miami" joins the Sunday lineup at 10 p.m. Oct. 3.

"NCIS: Los Angeles" is getting a two-hour premiere on Tuesday, Sept. 21, pushing the debut of "The Good Wife" back to Sept. 28.
