I checked the site code and everything I could see very carefully when I went back. The site is not an ecommerce site, so no shopping carts. No ads, I'm certain there was no DoubleClick code as I would have noticed that.
The only think I found was Analytics. The corporate ads appear to have stopped following me around this week. Thankfully. Still, the "interest based" ads lasted way too long. Google should know that people have short interest spans these days.
