College Music had 794 subscribers in April 2015, a year before Mr. Pritchard and Mr. Laxton started streaming. A month after they began, they had more than 18,440. In April 2016, they had 98,110 subscribers and as of last month, with three active live streams, they have more than triple that amount, with 334,000. They make about $5,000 a month from the streams.
The boys stumbled upon a new strategy, one that, in the past two years, has helped a certain kind of YouTube channel achieve widespread popularity. Hundreds of independently run channels have begun to stream music nonstop, with videos that combine playlists with hundreds of songs and short, looped animations, often taken from anime films without copyright permission.
