There are five terrestrial television channels and with the growth in cable, satellite and digital programming there are an enormous number of potential programmes, not to mention the non-broadcast market for corporate, training and educational productions. There has been a similar growth of radio stations. Although most radio programmes are music based, there are a number of talk shows that require research. The new media sector, producing CD-ROMs and the content of Internet sites, has grown in the last few years and is now a major area of employment.
