Since 1987, Houston Media Source has provided public access cable television programming in Houston, offering programming created by citizen producers 24 hours every day. HMS-TV not only provides these producers with a place to exhibit their work, it also gives these creative individuals the training and equipment they need to realize their visions. This approach produces a rich tapestry of programming, one which reflects the diversity and vitality of the Houston community. Each day, Houston Media Source viewers can enjoy programming focusing on a variety of topics: news, politics, culture, religion, arts, music, law, health, business, and science.

As part of its service to the Houston community, HMS builds a solid educational foundation for its citizen producers, providing instruction in a variety of topics, among them: media literacy, camera operation and technique, lighting, sound design, editing, storyboarding, script writing, studio operations, and mobile production.
