This licence lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This licence is often compared to open source software licences. All new works based on yours will carry the same licence; so any derivatives will also allow commercial use.

e.g. Tim creates some digital graphic designs and licenses them as Attribution-Share Alike. A class of students re-work Tim’s graphics as part of their individual assignments. Some of the students want to release their new designs online, but they must release them as Attribution-Share Alike also.
