Television is a medium of communication and communication is a means through which culture is spread, shared, maintained, repaired and transformed. Contemporarily, the term culture covers the domains of arts, sciences, beliefs, manner or even attitude of a group of people such as tribe, religious body or society. It can be defined as the sum total of way of life of a people such as festivals, dances, religion, language, norms/traditions etc. This study examined how the Nigeria Television Authority has been or not used in promoting Nigeria cultural values and heritage. The method adopted in the study is survey. The interview technique was used involving a total of 400 respondents drawn from the staff members of the NTA, Enugu zonal station, and the Station’s audience. Findings of the study revealed that television is a powerful medium through which a people can, through programming and content, share and export their cultural values for sustainable development, as well, a medium for eroding culture and tradition. It was further found that the NTA has not been sufficiently utilized to promote the Nigerian culture. The study recommended that mass media workers, particularly television programmes designers should sit up in the area of promoting Nigeria cultural heritage through TV programme content. Secondly, it is recommended that TV producers should endeavour to down play indecent dressing and violence, while emphasizing more of educative, informative, technological and entertainment in their productions.
