Lumen designed a scientific study where static, analog content was compared to digital, interactive content. The same information was presented in two ways: in our interactive content format, the Turtl Doc, and as a classic, static PDF. It found that readers engaged with the Turtl Doc for longer – and showed improved comprehension and information retention.
Since then, those findings have helped hundreds of marketers make the case for more interactive, effective content. So, we decided it was time to repeat the experiment.
