For the February 2013 sweeps, WGRZ widened its lead in the morning by 24%, in large part due to the addition of Melissa Holmes as co-anchor of "Daybreak". That program now has almost the same number of viewers as WIVB-TV and WKBW-TV's morning shows combined. WGRZ also further increased its lead as the #1 newscast for its early evening newscasts with anchors Scott Levin & Maryalice Demler. Only the late evening newscasts during the week trail WIVB-TV in viewership; however, WGRZ is still dominant in the key demographics which advertisers covet most. Viewership for WGRZ's weekend newscasts also places at a dominant #1, although as an NBC affiliate, it is subject to far fewer sports pre-emptions than its competitors, both of which carry more college sports on weekends as affiliates of CBS and ABC.
