The best of YouTube : the world's coolest, craziest and funniest clips

"YouTube is to video browsing what a Wal-Mart Supercenter is to shopping: everything is there, and all you have to do is walk in the door." (Time Magazine).

YouTube - and the 250 million videos (and counting) it hosts - is one of the 21st century's leading sources of entertainment, with people across the globe discussing which latest YouTube video is currently making them laugh out loud, cry with joy, or shocked in amazement.

As the world's most visited video sharing site, YouTube now has the power to create truly global celebrities - from Mao Mao the sneezing panda to Fenton the runaway Labrador, to Commander Chris Hadfield, who famously uploaded a video of him self singing David Bowie's "Space Oddity" all the way from the International Space Station to, of course, Justin Bieber, the biggest artist to be discovered on the site, and the first person to reach a billion views.

The Best of YouTube contains all your favourite clips - with QR codes for super-quick referencing - and is your indispensable guide to discovering the website's greatest, and most popular, videos. From the world famous and global viral hits to the highly creative and the not so well known, this is the perfect gift for YouTube fanatics or those new to the site.
