The correct answer is "narcotizing dysfunction." "Narcotizing" describes something as if it were affected by a narcotic drug, which induces sleep in the user. Media can have a "narcotizing dysfunction," which refers to making the public even more "sleepy" (less engaged), especially in regard to political participation. Since there is so much media online, it's easy for the public to become overwhelmed, confused, and eventually apathetic to all the messages from the media.
