Esurance, which ran the Advt after the superbowl, got more than 2 million tweets for the hashtag #EsuranceSave30. 200,000 of those tweets came in the first minute after the advt. They are awarding a cash of $1.5 Million to the lucky winner. Esurance, an American auto insurance company, also increased its follower count after the ad. The brand was trending on Twitter & this is a very creative way to reduce the ad spend and also to increase the social media presence.
