If you haven’t watched YouTube in a while—if you’ve joined the Amish, or you’re Edward Snowden—a lot has changed. Early on, the platform was a salmagundi of out-of-focus lifecasts. The viral hits were cats getting wet and one-offs like “Charlie Bit My Finger—Again!,” a 2007 video whose exposé of House of Atreus-style family strife has earned it more than eight hundred million views. (Spoiler alert: a baby bites his brother’s finger.) YouTube was adults with camcorders shooting kids being adorably themselves. It was amateur hour.
