In public opinion, we had a a guest speaker who is the head of social media for Target. He spoke about how he is working on getting the Target Pintrest page more reach. They are working with an individual who has millions of followers. She is repinning Target pins to get more followers.
This reminded me of the pull opinion leaders have. He said they are now getting hundreds of hits a day to the pintrest page, all because of one person. It reminded me of the differences between PR and advertising research lecture we had today. PR cares about the reach the woman at pintrest has because the a successful PR campaign tends to focus on increasing knowledge of the brand, and increasing "good vibes" surrounding the brand.
