Mac Tonight was the McDonald's character with a crescent-moon head who promoted nighttime restaurant visits.
Mac Tonight was created for a 1980s advertising campaign that encouraged customers to think of McDonald's as an evening destination. The moon-shaped head made the character immediately recognizable and visually communicated the campaign's nighttime theme.
The commercials presented Mac Tonight as a sunglasses-wearing singer and used a version of the song “Mack the Knife.” This musical approach set the campaign apart from McDonaldland advertising, which generally focused on colorful fantasy characters and children's promotions.
The character is often confused with Birdie because both had strong time-of-day associations. Birdie represented breakfast, while Mac Tonight represented evening dining.
