* “Sarah Palin’s Alaska” gave TLC its best series launch, but it was soundly outwatched Sunday night by another basic cable reality show, “The Real Housewives of Atlanta.”
* Palin garnered less than half the rating scored by “The Walking Dead,” which maintains its status as cable’s top scripted series and Sunday’s top cable show.
* “Undercover Boss” hit another all-time low. Last spring it consistently won its slot; now it languishes in fourth place. Its weakness seems to have hurt “CSI Miami,” which hit a new season (maybe series?) low.
* “Boardwalk Empire” remains pay cable’s top current series.
