I started this page in fall of 2013, with a couple of new ads, and a few older ones I remembered. But then I did a general YouTube search for Halloween commercials, and found some I'd forgotten, and some I'd never seen. Doubtless there are countless other ads I've forgotten, or never saw, which I haven't found, but would include here if I did. In 2015, I decided to just make a playlist on YouTube, to de-clutter this page. Some of the ads (particularly the older ones) have poor audio and/or video quality, but it can't be helped, I guess. I also eventually started a playlist called "Everyday Monsters," for ads that aren't about Halloween, but would be apt around Halloween. (I moved a few of those ads off the Halloween playlist, but most of them were never on it.)
Everyday Monsters: Starburst (zombie); Ray-Ban (vampires); Osteo Bi-Flex (Frankenstein); Geico (witch); Windows 7 (zombies); Sonic (vampire); Reese's (Frankenstein); Energizer (Wicked Witch); Sprint (zombie); Reese's (Dracula); Honey Nut Cheerios (Frankenstein); Nutrigrain (vampires); Geico (Dracula); Virgin Mobile (stalker); Energizer (King Kong); Sprint PCS (monster in the closet); Radio Shack (Frankenstein); Skittles (zombie); Geico (serial killer); M&Ms (Addams Family); Wheat Thins (yeti); Snickers (Godzilla); Verizon (Twilight); Five Star (zombies); Wonderful Halos (witch); H&R Block (zombie); Spectrum (4 ads, various monsters); Progressive (monster under the bed).
