Captions are text that is time-sychronized with the media. They convey all spoken content as well as relevant sound effects. Captions originated in the early 1980s from an FCC mandate for broadcast TV.

The 21st Century Communications and Video Accessibility Act requires all Internet programming that previously aired on television with captions to have captions online, as well.

The values of captioning include:
- Accessibility for deaf and hard of hearing
- Accessibility for ESL viewers
- Flexibility to view anywhere, such as noisy environments or offices
- Search
- Reusability
- Navigation, better UX
- SEO/discoverability
- Used as source for translation

Watch the slideshow to learn how to add captions to your videos using 3Play Media.
