People don't look to the TV Guide Nowadays it's all about seeing what their friends have posted on social channels. For brands, that means the potential for "earned media" is significant. If a video is compelling enough, they won't have to pay to show it to consumers; consumers will do that sharing themselves on social channels. Moreover, consumers are more likely to remember the brand involved if they came across it thanks to a social media recommendation.
In my opinion, I think social medias changed our daily lives greatly. We spent a numerous time on social media every day. Social media can help company’s save money by just posting their advertisement on Youtube. Social media also us to know about news all around the world.
