Katie Ryan's home office in Pittsburgh, Pennsylvania is pretty run-of-the-mill.

I just have a regular IKEA desk. I have a big TV up on the wall. I have a laptop stand with my laptop on it, and then I have a monitor stand that has two monitors on it.

There's a blanket on the floor for my dog,

you know. But the work she does at this desk is seen by millions of people every week.

I've done the Super Bowl a handful of times. I've done the Olympics many times. I just did the Oscars a couple

weeks ago. Any sporting event that you can think of, I've probably done it. Any major news event

that has happened, I have probably been involved in that somehow. Presidential funerals, presidential

debates. I remember when the bus and marathon bombing happened, the breaking news

was just constant. I think I was on the air writing without a commercial break for something

like three and a half hours. Ryan is a captioner. She writes the text transcripts that appear on

your TV screen when you turn on closed captioning.

She does this in real time.

Most people think their TV just does it.

They don't realize that there's a person like me sitting in a room with headphones on.

And people don't realize that it's happening live.

Like if I'm writing a news broadcast or a sporting event, maybe I have

like five seconds extra than you do when you're hearing it. And I have to write it at the same time

and try and keep up with all the speedy talkers that are out there. In some ways, it's a good business

to be in. One survey found that 50% of Americans

and 70% of Gen Z viewers

say they watch content with captions on most of the time.

But the industry is also rapidly changing.
