Social media may be the marketing channel of choice for restaurants today, but many chains once opted for loftier means. Like their roofs.

This week’s edition of Restaurant Rewind, Restaurant Business’ retro-focused podcast, looks back at restaurants' once-routine use of a particular color on the tops of their buildings as a marketing tool. Pizza Hut’s point of instant recognition was a red roof. Howard Johnson’s opted for orange. IHOP relied on light blue.

Podcast host and RB Editor At Large Peter Romeo takes listeners on a trip back to those days for a look at what was once a cookbook way of calling attention to a young concept. The quick report examines why the practice fell out of favor and how some brands are grappling with what those arresting roofs still say to the public about the concept they cap.
