Client: Sun-Maid Raisins
Insight: Young adults are always snacking, but rarely on raisins. There seems to be a stigma that dried fruits in general are for old people. Sun-Maid Raisins have been around for over a century; you might say they're the elderly of snack foods. As an honest brand, Sun-Maid could leverage this notion that their product is "old" by giving their veteran raisins a voice.
The one thing: Raisins are better because they're older
"Throwback Thursdays" would give Sun-Maid a chance to relate to younger adults
and still tie back to the aging process involved with making raisins.
