Best Buy Black Friday Tweet

Best Buy nailed user engagement with this old-school Vine campaign. They asked shoppers waiting in line on Black Friday to create short videos and tag them with #VineInLine. The best ones got retweeted. Boom—crowd content and buzz for free.

Why it works

• Turns boring wait time into a fun activity
• Uses customer creativity as free content
• Builds social proof right before a big sale
• Rewards participation publicly (RT = instant fame)

Real-world examples

• Starbucks’ #WhiteCupContest turned cup doodles into viral art and drove engagement.
• Chipotle’s “Guac Dance” challenge on TikTok became its biggest digital promo ever.
• IKEA used user-made dorm room tours on Instagram to fuel back-to-school buzz.
