This just in from TLC: The premiere of "Sarah Palin's Alaska" on Sunday night averaged 4.96 million viewers -- making it the No. 1 program launch in TLC history.
Premiere bested the 2003 series launch of "What Not to Wear," which previously held the record.
"Sarah Palin's Alaska" also brought in 1.6 million viewers among adults 18-49, but mostly skewed old, with the majority of the audience (3.9 million) over 35.
Show improved TLC's time slot average over the past six weeks by triple digits, the cabler said.
