I assume you mean between 2010 and 2020. As maxsaidit9999 said, i believe that the rise of social media will be one of the defining characteristics of the decade. I also think the decline of traditional news outlets will also be cited in tandem with the rise of SM. What I am most interested in, however, is what the social media landscape will look like in the 2020s. Almost every social media outlet is cracking down on free speech and I feel there will eventually be a backlash. There is also the fact that many social media platforms are only being held up by their stock price. Companies like Twitter and Snap have not ever turned a profit. Assuming there will be a market correction in the early 2020s (i firmly believe this will happen) it may take some of those platforms with it. Wether they will be bought by companies like Apple and Google or will just fall apart remains to be seen but I do not see an independent Twitter or Snap in 2025
