TLC's 'Sister Wives' gets love from viewers

TLC's controversial polygam-tastic reality show "Sister Wives" is the network's most-watched series premiere in a year.

"Sister Wives" pulled 2.3 million viewers, which isn't exactly "Jon & Kate Plus 8" territory, but nonetheless represents a fine number for the network. 

It's the biggest series opener since the network launched "Cake Boss," with TLC cheekily noting "Sister Wives" out-delivered all season premieres of HBO's scripted polygamist drama "Big Love" -- at least among women 18-34, if not other, more important measurements.
