Here's an announcement from CBS today...
The houseguests of BIG BROTHER: ALL-STARS have a new home on Sundays, one of several summer scheduling changes announced today by CBS.
The Saturday edition of BIG BROTHER: ALL-STARS will move to Sunday (8:00-9:00 PM, ET/PT), followed by the relocation of COLD CASE (9:00-10:00 PM. ET/PT) and WITHOUT A TRACE (10:00-11:00 PM/PT) to their new fall time periods, effective July 16. The move of BIG BROTHER: ALL STARS to Sunday warms the time period for another reality series in the fall when THE AMAZING RACE moves to Sundays at 8 PM.
The Tuesday edition of BIG BROTHER: ALL-STARS (8:00-9:00 PM, ET/PT) and Thursday edition (8:00-9:00 PM, ET/PT) will not change.
WITHOUT A TRACE will continue to be broadcast in its current Thursday time period (10:00-11:00 PM, ET/PT) through the remainder of the summer.
In other summer scheduling moves, the July 5 premiere of ROCK STAR: SUPERNOVA will be expanded to 90-minutes (8:00-9:30 PM, ET/PT), followed by a 90-minute CSI: MIAMI.
NCIS and THE UNIT will relocate to Fridays for the duration of the summer, effective July 7 with NCIS broadcast from 8:00-9:00 PM, followed by THE UNIT from 9:00-10:00 PM. (This is a temporary, summer-only move.)
Also, HOW I MET YOUR MOTHER will get two Monday airings, first in its regular 8:30-9:00 PM time period and another following TWO AND A HALF MEN (9:30-10:00 PM, ET/PT) beginning July 10. THE NEW ADVENTURE OF OLD CHRISTINE returns Aug. 7.
