Captions can be used in a variety of media, including:

Television: Captions are often used on television to provide a written transcript of the audio for people who are deaf or hard of hearing.

Movies: Captions are often provided in movie theaters for people who are deaf or hard of hearing. Some DVD and Blu-ray releases also include captions.

Online videos: Many online videos, such as those on YouTube, include the option to display captions. This can be helpful for people who are deaf or hard of hearing, as well as for those who are learning a new language or who may have difficulty understanding the audio due to a noise in the environment.

Live events: Captions can also be used at live events, such as concerts or conferences, to provide real-time transcriptions of the audio for people who are deaf or hard of hearing.

Printed materials: Captions can be included in printed materials, such as books or magazines, to provide a written transcript of an audio recording or to describe an image.

Overall, captions can be a useful tool for making media more accessible and inclusive for people who are deaf or hard of hearing, as well as for those who may have difficulty understanding spoken language or who are learning a new language.
