A high school teacher in the U.S., with 10+ years of experience, makes about $65,000 per year -- on average.<p>There are generally 180 days of school per year.<p>Let's say she teaches 5 classes per day, 20 students per class.<p>That works out to ~$3.60 per student per class. Classes run about 40 minutes each or ~$0.09 per minute.<p>I know there are many variables affecting this calculation but if screencasting is about delivering consise, high quality instruction, consistently, then $0.10 - $0.15 per minute does not seem unreasonable.<p>Nor should $0.20 per minute ($12.00 per hour). But it's interesting that it does.<p>Compare that to what an undergraduate student pays per minute for a lecture given by a TA to he and 200 of his closest friends.

Seems to be a trend that most screen casts are paid whereas most text based equivalents aren't. I guess this might be because people have expressed a willingness to pay for this type of content whereas text based blog type articles and tutorials are a lot harder to convince people to pay.

Considering that PeepCode sells their videos 9$ each and has cheaper options if you purchase a plan I find 14$ a bit steep for a video from someone I don't know as well.

I found this blog post that seems to provide a more in depth look at what is covered in the screencast: <a href="http://lostechies.com/derickbailey/2011/10/25/rebuilding-my-backbone-js-plugins-with-modules-srp-and-more/" rel="nofollow">http://lostechies.com/derickbailey/2011/10/25/rebuilding-my-...</a>

FYI - I had been incorrectly advertising the screencast as 120 minutes. It's actually 1:21 - 1 hour, 20 minutes. I'm terribly sorry about that. I've corrected the site.
