For years, I assumed captions were mainly for people who were deaf or hard of hearing, or for viewers watching something in a language they did not understand. If subtitles appeared when I started streaming a show, I treated them almost like an incorrect setting and quickly switched them off.
Apparently, I am increasingly in the minority.
Captions have become a normal part of watching television, films and online videos. Surveys suggest that a majority of Americans use them at least sometimes, while their use is particularly common among younger viewers. Look around a room where people are streaming something and there is a good chance that the dialogue is appearing at the bottom of the screen even though everyone can hear perfectly well.
At first, the explanations seem straightforward.
People say captions help them catch dialogue they might otherwise miss. Different accents can make comprehension difficult: Scottish English, for example, can challenge an American viewer, just as fast American speech can challenge someone elsewhere. Even within the same accent, actors sometimes speak quietly, background music competes with dialogue, and modern sound mixing can make individual words surprisingly difficult to distinguish.
Once, viewers simply accepted that they would miss a few words. We do that in ordinary conversation all the time. But streaming technology has changed expectations. If every word can instantly appear on the screen, why settle for understanding only most of them?
Think of a series such as “The Wire,” with its rapid dialogue, overlapping conversations and distinctive varieties of American English. Twenty years ago, I used to warn people from outside the United States that they might struggle to follow parts of it. Today, the solution is obvious: turn on the captions.
There are practical reasons as well. If you are watching something on your phone in a public place—and possess the basic courtesy not to make everyone around you listen to it—captions are enormously useful. They also make it possible to follow a video while simultaneously texting, scrolling or doing something else. I cannot claim to understand the appeal of dividing one’s attention quite so aggressively, but clearly plenty of people do.
Still, none of these explanations quite captures what is happening.
I have watched groups of young people sitting comfortably in a quiet room, the television loud enough for everyone to hear, watching “The Simpsons” with captions turned on. The dialogue is hardly obscure. Nobody is whispering. There are no elaborate overlapping conversations to decipher. Yet the captions remain.
The same thing happens with older viewers. I sometimes watch old films with a Russian couple whose English is extraordinarily good. Older soundtracks can be muddy and full of hiss, so captions genuinely help them. Fair enough. But when they are not there, everyone else still wants the captions on.
That is when the phenomenon becomes more interesting. Perhaps captions are no longer merely an accessibility tool. They have become part of the way many people consume audiovisual information.
And perhaps that tells us something unexpected about reading.
We are constantly warned that people—especially younger people—no longer read. Attention spans are supposedly collapsing. Books are losing ground to short videos. Screens have displaced text. The familiar story is that visual culture is gradually pushing reading aside.
Yet millions of people are voluntarily adding written language to an activity that does not require it.
They are watching and reading simultaneously.
Captions may actually make television a hybrid medium. The viewer hears the actor, watches the performance and reads the dialogue at almost the same moment. The written words reinforce the spoken ones, reducing uncertainty and making information easier to process. What appears to be a strange new habit may simply reflect a preference for receiving the same information through more than one channel.
There may also be a deeper technological change at work. We now live in an environment saturated with written language. Text messages, social media posts, search results, notifications, comments and captions surround us throughout the day. For generations raised with smartphones, moving constantly between written and audiovisual information is not unusual. It is simply how communication works.
In that sense, captions do not interrupt the viewing experience. For many people, they complete it.
There are costs, of course. Once captions are on, the eye is naturally drawn toward them. Instead of studying an actor’s expression, the landscape or the composition of a shot, viewers may spend part of every scene reading the bottom of the screen. A joke can also lose something when its punchline appears in writing a fraction of a second before the actor delivers it. Suspense, rhythm and surprise are sometimes casualties of knowing the words before hearing them.
This is probably why some of us still find captions irritating. Film and television were designed primarily to be watched and heard, and constantly reading the dialogue can feel like placing another layer between ourselves and the performance.
But habits change along with technology. Younger viewers may not experience captions as an intrusion at all. If they have spent much of their lives watching short videos accompanied by text on the screen, audiovisual material without written reinforcement may actually feel incomplete.
So perhaps the rise of captions should complicate our familiar anxiety about the death of reading.
People may be reading fewer novels, newspapers or long essays than previous generations did. That is a legitimate cultural concern. But it does not follow that written language itself is disappearing from everyday life. In some respects, we may be reading more frequently than ever—just in smaller fragments and in places where earlier generations would never have expected text to appear.
The television screen is now one of those places.
For decades, television was portrayed as reading’s great enemy: the passive screen that would eventually defeat the printed word. Instead, something rather amusing has happened. Viewers have begun putting the words back onto the screen themselves.
So who says reading is dead? We have reached the peculiar point where many people will not even watch television without doing some reading at the same time.
