Super Bowl 50 is in the books but the buzz on those super ads are just getting started.

According to iSpot, Mountain Dew’s commercial cost nearly $5.5 million to air but it generated more digital activity than any other Super Bowl commercial.

In response, Colonial Williamsburg tweeted this: “Forgetting is not an option! Every generation has a defining moment. For us: 9/11. Knowledge of history = civic responsibility.
