Answer:

Given the thorough integration of social media into the lives of the majority of American teens, it is no surprise that these sites play an important role in the establishment of friendships and the everyday back and forth of peer relationships. This chapter takes an in-depth look at the role of social media in teens’ friendships, looking at teen friendships more broadly defined.

Social media is an important venue for interaction and conversation among America’s youth. Fully 76% of all teens use social media. Facebook is the dominant platform, with 71% of all teens using it. Instagram and Snapchat also have become increasingly important, with 52% of teens using Instagram and 41% using Snapchat. One-third of American teens use Twitter and another third use Google Plus. Fewer teens use Vine or Tumblr.

Social media plays a critical role in connecting teens to new friends, allowing teens to learn more about new friends and get to know them better. Nearly two-thirds (64%) of teens who have made a new friend online say they have met new friends on a social media platform. Two-thirds (62%) of teens say they’ve shared their social media username with a brand new friend as a way to stay in touch.

Beyond making new friends, social media is major way that teens interact with their existing friends. More than nine-in-ten teens (94%) say they spend time with friends on social media. Fully 30% say they spend time with friends on social media every day, and another third (37%) say they do so every few days. When asked to rank the ways they communicate with friends, social media sites like Facebook or Twitter are one of the top ways of communicating with friends for two-thirds (66%) of teens.
