What do the terms EGD/XGD refer to?
Here are two articles describing Environmental Graphic Design and Experiential Graphic Design.In 2014 SEGD changed the "E" from Environmental to Experiential. This was done to recognize the rapid expansion over the last decade of the scope of what this profession does. Experiential encompasses all of Environmental Graphic Design, but expands it to include digital technologies, content (such as video, images and stories) and most importantly the notion of interaction.
