Rising demand for accessibility solutions

The captioning and subtitling market is experiencing significant growth due to the increased awareness and legal requirements of accessibility. Captioning is necessary to make video content accessible to the deaf or to people with hearing impairment. Governments across the globe are enacting legislation such as the Americans with Disabilities Act (ADA), mandating accessible video material for deaf populations. This regulatory push, combined with the increased societal focus on being inclusive, drives demand for efficient captioning and subtitling solutions in a variety of industries, including education, entertainment, and corporate communications. For instance, on March 27, 2025, 3Play Media, the industry leader in media accessibility solutions, announced the launch of its global linguist marketplace along with its cutting-edge, AI-enabled accessibility and localization solutions for video-forward businesses across media & entertainment and enterprise. This timely release comes as the European Accessibility Act (EAA) is set to take effect in June 2025, placing 3Play Media at the forefront of helping organizations meet new captioning and audio description requirements in multiple languages.

Globalization and the Rise of Video Content

The advancement of streaming technology and online video platforms has fundamentally changed the watching patterns of audiences across the globe. Content does not remain region-bound anymore, and the call for localized editions of videos, movies, and educational content is growing exponentially. Subtitling is a means to overcome the language barrier to make content producers reach a vast global audience. This is also driven by the growing popularity of user-generated content, which usually requires subtitling to facilitate clarity and access for viewers across different linguistic backgrounds.

The Impact of Technological Advancements

The world of captioning and subtitling is facing a fundamental change with the growth of artificial intelligence (AI) and machine learning (ML) capabilities. Automated speech recognition (ASR) technology is becoming increasingly sophisticated, enabling faster and more cost-effective captioning and subtitling workflows. Although human checks and edits are still necessary for quality assurance, AI-based solutions are saving innumerable hours of effort and time spent in the process, opening captioning and subtitling to scores of more content producers. For instance, in 2021, RWS, the world’s leading provider of technology-enabled language, content management, and intellectual property services, and CEDAT85, pioneers in speech recognition technology, announced a new partnership and the launch of a live subtitling and captioning solution for online meetings and events. The offering allows multilingual participants to actively collaborate and engage with each other in real time – in their own language – without linguistic barriers.

Enhanced User Experience and SEO Benefits

Apart from accessibility and globalization, subtitling and captioning also bring tangible returns to user participation and search engine optimization (SEO). It is proved through various studies that such videos are watched longer, and captions help improve the understanding and memory of content. Additionally, search engines, such as Google, are capable of crawling text on captions, so videos get easily discovered and get better rank in search results. This double benefit makes captioning an asset to organizations and businesses wishing to achieve maximum impact for their video material.

Government Regulations and Standards

The captioning and subtitling market is significantly influenced by government regulations aimed at ensuring accessibility. In the U.S., the Federal Communications Commission (FCC) has created rigorous captioning standards for television shows, with requirements for broadcasters and cable providers to provide captions for almost all video programming. Similarly, the European Accessibility Act of the European Union requires accessibility standards to be set for television shows as well as video content. These standards continue to develop and expand, further fuelling the need for captioning and subtitling services.

Specific Examples of Regulatory Influence

The Americans with Disabilities Act (ADA) in the United States has also contributed to broadening captioning mandates beyond over-the-air broadcasting. Title III of the ADA, which makes discrimination on the basis of disability illegal in places of public accommodation, has been interpreted to cover online video content provided by commercial entities, creating expanded demand for captioning for websites and streaming services. Within Europe, the Audio-visual Media Services Directive (AVMSD) encourages higher levels of accessibility of audio-visual services, setting the stage for member countries to pass national legislation that requires captioning and audio description for television and video-on-demand services.
