Paying With Privacy

Now have students access the student chapter How Are You Paying?

Have them use the interactive tool to list all of the paid apps (ones that you pay to purchase, that have a subscription fee, or that include in-app purchases) that they use in the left-hand column, and all of thefree apps (that you do not pay money for in any way) in the right- hand column. (If they do not know whether an app is paid or not, have them put it in the free column.)

Now ask students: Which list is longer? Have students name some of the free apps that were included in the right-hand column and list them on the board. They will likely include social networks such as Instagram and Snapchat.

Ask students: If these apps are free, how do you think they make money? Let students suggest a few answers without indicating whether they are right or wrong.
