Social media is undoubtedly a significant part of a teenager's life. It is a way of expressing ourselves, communicating with friends and keeping up to date with current affairs. Although social media is often condemned, particularly by adults, it is a vital part of feeling connected in the world we live in today.

Daniel Goleman, an author, psychologist, and science journalist, wrote: 'Smart phones and social media expand our universe. We can connect with others or collect information easier and faster than ever.'

Social media is constantly evolving. From its beginning over 10 years ago, never would we believe it will have such a powerful effect on our lives like it does today. Bulletin Board System (BBS) was its forefront – despite being created before the web. Since then, the internet has enabled Facebook, Twitter, Google+, Tumblr, Instagram plus many more platforms to transform social media.

Many other forms of social media are challenging Facebook's position as king of the social media. It is even predicted that by 2016 Google+ will surpass Facebook on 'social sharing'.

In 2013 on average there were 500 million tweets sent on a daily basis whereas only 55 million Facebook statuses written per day. Although Facebook still has more 'active users' how long will that last? Has Facebook's time come and gone?

Facebook has said they are seeing a 'decrease in daily users, specifically among teens'. Personally, all I use Facebook for is to watch vines and to keep in contact with people. However I have WhatsApp and iMessage for this - so how relevant actually is Facebook?

WhatsApp has 350 million monthly active users globally, making it the biggest messaging app in the world by users. Mobile operators have lost $23bn in SMS revenue in 2012 due to messaging apps. Who knows what other aspects of social media will soon be affected? I asked 30 of my friends about the topic and 96% of them said that Facebook is dying down and they now use Twitter. This is very much the case of many teenagers both in Norfolk and around the UK.
