The current age is called the Information Age. This has caused various media outlets to make efforts in this competitive environment (i.e. media competition) to have a larger share of the world audience. This is only possible when the media can play out an active and distinguished role in the society. In this competitive space, what makes a particular media form in the world distinguished is their reputation. The human resources of a media outlet are among the most important and advantageous aspects of competition. The present paper aims to study the role of development of human resources as the most important factor affecting the public acceptability of the Islamic Republic of Iran (IRIB)'s Central News Unit. The outcome of actions, capabilities, abilities, skills and knowledge of news media staff are disseminated in the information market, causing the media to achieve fame. The paper attempts to examine the role of media's reputation as the most important factor affecting the development of human resources in this field. Therefore, this paper seeks to provide a model of human resources development in the national news media, which can consequently bring in reputation for the media. Our results indicated that a significant relationship does exist between these variables which in itself indicates the validity of the proposed model.
