Just got this fascinating link from a library colleague. It's from the Museum of the Moving Image. How about let's study the visual and rhetorical techniques of campaign ads as part of information literacy.
"The Living Room Candidate contains more than 300 commercials, from every presidential election since 1952, when Madison Avenue advertising executive Rosser Reeves convinced Dwight Eisenhower that short ads played during such popular TV programs as I Love Lucy would reach more voters than any other form of advertising. This innovation had a permanent effect on the way presidential campaigns are run."
