Multimedia businesses create, produce or supply content that combines different forms of media, such as text, photography, graphics, animation, sound and video. Their work may be used for websites, social media, advertising, presentations, training, events, exhibitions or interactive applications. Services can include planning and scripting, filming, photography, audio recording, graphic design, animation, video editing and preparation of content for digital or printed use. Some businesses in this category also provide technical services and equipment for presenting multimedia content. This may include installing or operating screens, projectors, speakers, lighting, interactive displays and video conferencing systems, as well as producing presentations or digital signage. The range of work varies: a provider may focus on creative production, technical support, equipment hire or a combination of these.
