Earlier this month, vlogger Jake Paul launched his own Edfluence serviceto teach fledgling online-video creators the tricks of the trade. Now he's been joined by YouTube musician Peter Hollens.

Hollens has launched his own platform, the Hollens Creator Academy, which will offer a suite of courses addressing various aspects of building an online-video career.

Tubefilter notes that the academy will cost $129 to join, providing its students with access to the courses, starting with a 'How To Make A Living Online' course that includes 77 lessons spread over 11 modules.

Its article suggests that more than 1,000 people have already signed up, which suggests at least $129k of revenues for the Academy even at this early stage of its rollout.

While there's plenty of free material available – not least on YouTube, with its own selection of training videos and exercises for creators – it seems there's also a market for paid courses, especially those fronted by established social stars.
