More and more advertisers are using social media and other technology to push their advertising these days, including twitter and foursquare. Take a for example Sports Authority; this coming black friday they are going to be tracking who checks in to their locations, and giving away 20 $500 gift cards to Foursquare users that check into their location.
To win, customers will have to be checked in to their local Sports Authority between 10:00am and 3:00pm, and listen for their name to be announced over the in-store speakers system, and then present their photo ID to claim their prize. Sports Authority is also doing a YouTube home page promotion, a FaceBook promotion, and some special twitter promotions as well. For more details check out the Sports Authority website and circulars.
