To make is point, Silverstein is showing a series of then and now juxtapositions. Like the Super Bowl image of the commercial that introduced the Mac computer in 1984, and the current new millennium version of a GoDaddy commercial babe.
Another juxtaposition: Walter Cronkite to Bill O'Reilly.
Or JFK to Sarah Palin. ("I think whoever we elect for president should at least know how to read a book," he quipped.)
Then (Apple's "1984" Super Bowl commercial)
Now (GoDaddy's circa whatever commercial)
The first slide brought to mind the comparison of Nike's "Run Like a Girl" slogan for the women's marathon. I know a a good hand full or serious runners who were offended by this, finding it to be trite & demeaning when they want to feel strong & accomplished.
