In our first-ever ranking of the top-paid YouTube stars, we have uncovered the 10 channels that have managed to earn the most from their Internet aspirations. The minimum to make the list? $2.5 million in pretax earnings in the year ending June 1, 2015.

The list measures earnings before subtracting management fees and taxes. Our figures are based on data from Nielsen, IMDB and other sources, as well as on interviews with agents, managers, lawyers, industry insiders and the stars themselves.

These 13 DIY filmmakers—directors, producers, actors all rolled into one—have made millions doing what members of older generations may consider more play than work.
