This comes from mediaweek.com:
The WB�s Roswell moved to Monday with a 4.0/ 6, besting the second half of UPN�s Monday sitcom slate � Grown Ups (3.0/ 4) and The Parkers (2.6/ 4) � by a whopping 43 percent. Although Roswell slid 31 percent from 7th Heaven, the 69 percent retention is better than anything else The WB has aired here this season (including Safe Harbor, Jack & Jill, Brutally Normal, Zoe and Popular). This is a positive Monday start for Roswell.
