When Beyonce announced her pregnancy, a multistep flow of media effects became evident. Beyonce is an opinion leader to the public, which includes her beloved fans. Once she announced she was expecting, that information was captured by the media and influenced those who use social media secondhand. Although they might not have heard it from her in person, the news made its way down the chain and eventually onto Twitter and Facebook, making it accessible by all. The multistep flow model is one way the media impacts media usage.
