Different Material Editor Views

I am seeing two different versions of the materials editor properties. Can someone tell me why this is, and how I can switch between the two?


Different render enginbes which each have their own material system. Image on the left from the Blender Render engine and the image from the right from the Cycles Render engine. Change the renderer at the top of the blender interface

Thank you for your help!
