What is the drawing style called that is used in the RSA Animate lectures?

See some videos here: http://youtube.com/playlist?list=PL39BF9545D740ECFF

I don't think they are standard caricatures, but I have seen similar styles elsewhere, but I can't remember where and I am not sure what to search on to see more of the style.

Answer

The RSA Animate videos are created by CognativeMedia using ydraw.

This style of is often referred to as "animated vignettes" named after "animated narrative vignette," an instructional technology used in education.

An animated narrative vignette (ANV) is an instructional technology used to motivate and facilitate role-playing, problem solving, and discussion. Teachers develop the ANVs to present in class or in online training. Students might also create them in experiential learning exercises. They provide computer animation representations of teachable situations that encourage critical thinking and may also provide an instrument for assessing attitudes and behaviors. Vignettes have been used to teach mathematics and science, management skills, problem solving, and character education.
