For live broadcast television, closed captioning is typically provided by specialized real-time captioning vendors hired by the broadcaster, network, or program producer. The captions are generated as the program airs, usually by stenographers/stenocaptioners, voice writers, or increasingly by automated speech-recognition systems with human oversight.
Some established U.S. providers include:
The FCC doesn't itself provide the captions. Rather, its rules place responsibility on the applicable video programmers/distributors to provide compliant captioning, and specifically establish best practices for real-time captioning vendors and captioners.
If you're asking who captions a particular network or station (for example, ABC, CBS, NBC, CNN, or a local Chicago station), tell me which one and I can look up its captioning provider.
Providing closed captioning for live broadcast television (such as news, sports, and live entertainment) requires real-time synchronization, high accuracy to meet regulatory standards like the FCC , and specialized stenographic or voice-writing professionals.

For live broadcast television, closed captioning is typically provided by specialized real-time captioning vendors that work with television networks, local stations, cable channels, and broadcasters.
Some of the major providers in the U.S. include:
For a live news program, for example, the broadcaster sends the program audio to the captioning provider. A captioner—or increasingly an AI system supervised by captioning professionals—converts the speech into text in real time. The resulting caption stream is sent back to the broadcaster and encoded into the television signal.
In the U.S., the FCC places primary responsibility for television closed captioning on video programming distributors, although the actual captioning work can be outsourced to a third-party vendor.

Several companies provide real-time closed captioning for live broadcast television in the U.S. The major providers include:
For a live program, a stenographer/certified broadcast captioner or an automated speech-recognition system with human oversight converts the program audio into text in real time. The text is then sent to the broadcaster's caption encoder and transmitted along with the television signal. Modern providers increasingly use a combination of AI and professional captioners.

If you mean companies that provide the actual real-time captioning feed for live broadcast TV, there are several established providers in the U.S. They typically use stenographers (steno captioners), voice writers, and/or automated speech recognition (ASR), with the caption data sent to the station/network's caption encoder.
Some notable providers include:
There is also a broader DCMP directory of captioning service vendors, maintained through the U.S. Department of Education's Described and Captioned Media Program. It lists numerous captioning vendors, although inclusion isn't an endorsement.
For a live newscast, for example, the workflow is generally:
TV station/network → live audio → captioning provider → real-time captions → caption encoder → broadcast signal → viewer's TV
The FCC's rules specifically address real-time/live captioning vendors and set quality expectations around accuracy, synchronicity, completeness, and placement.

Prominent Live Broadcast Captioning Providers
If you are looking for a service provider, would you like information focused on AI-automated solutions or traditional stenographic human captioners , and for local or national broadcast?
For live broadcast television, closed captions are typically supplied by specialized real-time broadcast captioning companies. The captions are generated from the live program audio and sent back to the broadcaster, where they’re synchronized with and encoded into the TV signal.
Some providers include:
For genuinely live programming—such as a newscast, sports game, or breaking-news event—the captioner generally receives the program audio with very little delay. Traditionally, a stenographic captioner listens and writes using a stenotype keyboard, producing text at very high speed. Another method is respeaking, where a captioner repeats what is being said into speech-recognition software. Increasingly, broadcasters are also using AI/automatic speech recognition, sometimes with human oversight.
The resulting caption data is then fed into a caption encoder, synchronized with the video, and transmitted as closed-caption data. The viewer's television or set-top box decodes it and displays the captions.
If you're asking because you're interested in working as a live TV captioner, I can also explain which companies hire captioners, what certifications are typically required, and what the pay looks like.
