Playboy, Whiskey & Instagram.

If you visit between now and St. Patrick's Day (March 17), you'll see ads for Tullamore D.E.W., the blended Irish whiskey. Then, if you jump onto Instagram, you'll be retargeted with a 30-second video commercial from the same marketer.

When Playboy's sales reps inked Tullamore D.E.W. for the brand's second straight St. Patty's Day campaign on the lifestyle magazine's properties, they included an Instagram extension for the first time. After the deal was in place, they bought Instagram inventory for the whiskey's video that's appearing under the Playboy banner.
