Apple debuted a new iPod and iTunes television commercial during tonight’s Saturday Night Live on NBC. It featured the new single “Feel Good Inc” by the Gorillaz. Like the previous ads, the spot features silhouetted iPod-toting dancers in front of colorful backgrounds — only this time they’re all on roller skates. This is the first new iPod commercial since January’s iPod shuffle ad, and the first for full-size iPods since October’s ad featuring U2. Apple has yet to post the new commercial. Update: The ad is now available on Apple’s website.
