Nowadays, Social Media is getting more important. Most of people have facebook or twitter accounts, maybe both. I found most of my friends spent more time on these social media rather surf on net. They are "addicted" to use Social Media for getting the latest updates from their friends. In the old time, we use the banner ads on the websites, because a lot of people like to browse the websites. Nowadays, we need to use Social Media Marketing to reach our potential customers, because so many people are using Social Media. Moreover, the Social Media can have more interactions between users and vendors to provide the useful information.
