Social media, as I am sure most of us know, is any social platform that is used for people to connect with others through news, statuses, pictures and videos. The other side of social media is the advertising side and most platforms have either organic advertising (not paid for) or sponsored advertising (paid for). The cost of a sponsored advert is cheap compared to traditional marketing methods and the budget can usually be determined by the advertiser.
The biggest benefit of social media is, however, the reach an advert can get. You can, without blowing your entire yearly marketing budget at once, advertise to people all around the world and for a long period of time.
The most popular Social Media Platforms are LinkedIn, Facebook and Instagram.
