Early media theorists can help us to link the past and present of media literacy to pose new questions and gain new knowledge. Historian, author and Librarian on Congress Daniel Boorstin (1914-2004) played an important role in increasing public awareness of the constructed nature of media representations. Connections are explored between constructed reality, technological advances, media literacy education, and the current work of media scholar Douglas Rushkoff on "presentist society." Daniel Boorstin helped recognize the changing nature of knowledge in an image-saturated environment and influenced a new generation of theorists, scholars and educators who have advanced the field of media literacy education.
