You've probably heard the news that GM is ending the Pontiac line of automobiles. Here's a commercial from their glory days, the 1980s. And I mean the commercial screams 1980s.

You served Jim Rockford and Michael Knight well.

Recently, TV columnist Aaron Barnhart took note of the fact that Oprah Winfrey's show is sinking in the ratings. Her talk show, which is the centerpiece of her multimedia success -- a success that has made her the richest woman in show business -- has been losing ratings consistently for the last six months. At first blush, the politically minded of you might think it's because she endorsed Democratic presidential candidate Barack Obama, but I think it's more than that. After all, if anything, the vast amount of grassroots support that the Senator from Illinois has engendered might be a plus for Oprah rather than a minus.
