According to research from UCLA, teenage brains' reward circuits were more active when teenager's photos were liked by more peers. This has both positive and negative features. Teenagers and young adults befriend people online whom they don't know well. This opens the possibility of a child being influenced by people who engage in risk-taking behavior. When children have several hundred online connections there is no way for parents to know who they are.[107]

News media and television journalism have been a key feature in the shaping of American collective memory for much of the twentieth century.[90][91] Indeed, since the United States' colonial era, news media has influenced collective memory and discourse about national development and trauma. In many ways, mainstream journalists have maintained an authoritative voice as the storytellers of the American past. Their documentary style narratives, detailed exposes, and their positions in the present make them prime sources for public memory. Specifically, news media journalists have shaped collective memory on nearly every major national event – from the deaths of social and political figures to the progression of political hopefuls. Journalists provide elaborate descriptions of commemorative events in U.S. history and contemporary popular cultural sensations. Many Americans learn the significance of historical events and political issues through news media, as they are presented on popular news stations.[92] However, journalistic influence is growing less important, whereas social networking sites such as Facebook, YouTube and Twitter, provide a constant supply of alternative news sources for users.
Social media may have been influenced by the 1840s introduction of the telegraph in the US, which connected the country.[10] ARPANET, which first came online in 1967, had by the late 1970s developed a rich cultural exchange of non-government/business ideas and communication, as clearly evidenced by ARPANET#Rules and etiquette's "A 1982 handbook on computing at MIT's AI Lab stated regarding network etiquette," and fully met the current definition of the term "social media" found in this article. The PLATO system launched in 1960, which was developed at the University of Illinois and subsequently commercially marketed by Control Data Corporation, offered early forms of social media with 1973-era innovations such as Notes, PLATO's message-forum application; TERM-talk, its instant-messaging feature; Talkomatic, perhaps the first online chat room; News Report, a crowd-sourced online newspaper and blog; and Access Lists, enabling the owner of a notesfile or other application to limit access to a certain set of users, for example, only friends, classmates, or co-workers. Tom Truscott and Jim Ellis conceived the idea of Usenet in 1979 at the University of North Carolina at Chapel Hill and Duke University, and it was established in 1980.
