This question is frequently asked, albeit very relative. Here are some of the reasons why we think YouTube has gained so much traction:  • Huge global reach  • Easy to share videos  • Not required to sign up in order to use  • Easy to use on mobile, desktop, web browsers, and TVs • Potential to make money • Ability to share unique and longer content  YouTube has been popular pretty much from the get go; they were founded in February 2005 and saw their first video with a million views in October of 2005, making the huge power that YouTube has in marketing and viral sharing very clear.
