Mark Allen Peterson of in the Department of Anthropology at Miami University published an article in the Summer of 2011 comparing the media ecology of 1970s Iran to that in Egypt in 2011. The article, titled "Egypt's Media Ecology in a Time of Revolution" looks at the difference that social media made in the Egyptian uprising and makes two observations: social media extends the "grapevine" network and that social media, despite the result of the uprising, completely changes the "mediascape" of Egypt. One dramatic difference between the two uprising noticed by Peterson is the ultimate position of the media of choice during each in the end. On the one hand, Iran's news media, the primary source of information at that time, reverted to its original role, while the Egyptian use of social media changed the media of choice for Egypt.
