It's hard to believe YouTube is turning 10-years-old.
The video juggernaut celebrates its 10th year of being open to the public this month and, in honor of the anniversary, its spotlight channel has compiled some of the most memorable and must-see moments from the last decade and mixed them perfectly to Blackalicious' Alphabet Aerobics. Along with all the viral videos, the montage also uses various themes that have made the site special such as beauty, gaming and dance.
