 Dear students, now we are going to start the next module of our course which is social media in everyday life. As you all know that social media has become one of the biggest reality of the 21st century and it is considered as the significant aspect of our social life. Now you cannot imagine the social life without social media. We are heavily dependent on social media in our day to day routine life. And due to this we have generated a new kind of culture and a set of behaviors which is particularly relevant to the social media adoption and the social media's usage. And due to this new kind of social issues, problems and challenges have also been generated and created. And these challenges or problems we have come to know that at our levels, at individual level, at institutional level and at a communal level. That is to say, since the adoption of social media has become so widespread, where different kinds of behaviors have been generated, different forms of new interactions have been generated, new ways of communication have been generated. Due to this new social issues have also been created and when we talk about social issues, they are at the individual level as well as at the social institutional level and at a whole society as well. From now on, the next topics we will cover will be how social media has been generated, how behaviors have been generated, new forms of interactions have been generated, and how social problems or pathologies have been generated.
