friends and family, shop, get the news, or research issues? What is gained and lost by relying
so heavily on search engines—typically Google—as our primary gateway to information? Given
the customization of Google, the same search when conducted by different users can produce
different results (a point the chapter on agenda-setting theory makes when discussing Eli
Pariser’s notion of filter bubbles).
Nearly every day, stories seem to break about the mining and scraping of customer
data based on their social media profiles or their Internet history. As we write this, the
relationship between Cambridge Analytica and Facebook is a big news story, with Facebook
CEO Mark Zuckerberg testifying before Congress about how the social media giant uses its

changed the course of human history. You might try asking your students to generate a list of
other candidates for the game-changers. In McLuhan’s list, certain human innovations
purposes), antibiotics, particularly penicillin (which revolutionized medicine), optical lenses (for
magnifying and microscopic applications), paper, gunpowder, nuclear fission, air conditioning
(would Andrew want to live in Texas without it?), or semiconductors.
Part of McLuhan’s appeal was a tangible connection between the inventions on his
list—each tackled communication questions. With these alternate ideas or those you compile
with your students, you might see if you can identify a common element. How has life been
altered by the inventions? For example, what if, instead of ways we communicate, the
