Sarah Palin's “unprecedented negatives” are starting to spread to her TLC reality show, Sarah Palin's Alaska.

Her show's first episode drew five million viewers, making it the highest-rated premiere the network had ever had. The ratings for Palin's second episode fell off a cliff on Sunday, indicating that viewers were curious about her program, but disinclined to stick around:

Sarah Palin's Alaska fell 40% on Sunday night to 3 million viewers.

Not many were in the key adult demo either. Only 885,000 viewers were ages 18-49, dropping 44% from last week.

In fact, the median age of the show is 57 -- that's 15 years older than TLC's average.

Compare Palin's ratings to that of AMC zombie thriller The Walking Dead, which on Sunday drew 4.8 million viewers for its fourth episode, half in the lucrative 18-49 demo.

Sarah Palin's Alaska just doesn't seem to be the kind of horror show Americans are interested in.
