The first week of daylight saving time is almost over and the Big 4 must be hopeful that viewers are settling into the sunlight shift as almost everyone took a hit (or a slap) last night. There were family dinners and bruised egos on CBS’ The Big Bang Theory (4.4/16), and the network also had ACC Tournament college basketball preemptions in several markets across primetime. All of which saw the highest-rated and most watched Big Bang (16.08 million) dip 8% among adults 18-49 and down 11% in viewers from last week. Also on CBS, the fourth week of The Odd Couple (2.6/9) took a 13% stumble. Following a BBT encore, a new Mom (2.3/7) was up 5% from its March 5 show.
