Love it or hate it, 2013 will be remembered as the year of the selfie.
From Beyonce and Kim Kardashian to President Barack Obama and Pope Francis, everyone has been getting in on the narcissistic portrait action, helping to make the phrase Oxford Dictionaries' Word of the Year.
The selfie is nothing new, but the trend has exploded in recent years because of the rise of camera phones including, most importantly, Apple's front-facing camera in 2010. Add Instagram filters to the mix and the world of social media has become a hotbed for mainstream narcissism.
But there have been unlikely followers of the trend, too. In August, the Pope posed with a group of teenagers at the Vatican, creating the first-ever papal selfie.
