Recently, several food brands have been all over it, trying to capture the wistful hearts of Millennials with these mascots: After 21 years, KFC brought brand mascot Colonel Sanders back to their advertising, with new TV ads starring former &#8220;Saturday Night Live&#8221; comedian Darrell Hammond.&#160; After 13 years, McDonalds brought back the Hamburglar, and gave him a sexy new makeover that has people talking. And Oreo launched a new 90-&#8216;s style animated character called S'morey, the Unidentifiable Forest Creature. The character himself is new, but it&#8217;s definitely a throwback to a different time.But food brands aren&#8217;t the only ones who can try to harness people&#8217;s love of the past. Just last week, #InThe90sIThought started trending nationally on Twitter, with numerous brands including Keds, Bath &amp; Body Works&#160;and Polaroid jumping in with real-time content.&#160;This week, on Mindshare&#8217;s Culture Vulture Live, we explore how nostalgia can help your marketing - and look at the key tips for brands on how to get it right.
