Abstract: This application is for an electronic annotation system for annotating (by text, picture, or video) electronic digital content and sharing the annotations as an account owner with third parties without violating any copyrights of the digital content owner. Rather than sharing the electronically annotated digital content with third parties, only an overlay with the electronic annotation is shared with third parties as an account owner. The third parties must have their own legally obtained copy of the digital content. The third parties can open the annotation and independently access the underlying digital content, thereby spatially integrating the two on the third parties' computer screens.
