This PowerPoint covers what market segmentation is and why it is used. There are a lot of pictures. I also have incorporated links to Unilever and Pepsico's sites to help explain global geographics. There is a slide that I use with a SMARTboard with my class, but you could print it for students to use individually. I also found a link for a video online that covers the importance of market segmentation. The video also includes a quiz that you can do as a class or have students do individually.
