I read the article Tell your work story with an infographic by Hutch Carpenter and found that infographics are pretty useful to convey information about topics or people. But I doubt that infographics can be used for commercial purposes. This is why:
- Infographics are not usually used in business context.
- Infographics are not interactive. Websites or microsites can offer more interaction with the visitor.
If your value proposal is simple enough to fit into an infographic (which it should be), infographics will be a good add-on to your business communication, but will not be sufficient.
