INTRODUCTION    
1.1     Background to the Study  
This work intends to assess the effect of news commercialization on news credibility in the broadcast media, with particular reference to Africa Independent Television and Nigerian Tribune using them as a case study. The study intends to find out whether the commercialization of news affects its credibility and objectivity and equally to know if it encourages the “Brown envelope syndrome”, accuracy, balance, fairness etc. whether those who cannot afford to pay the media have the opportunity and chances to broadcast their events on air via Mass media of communication, such as the electronic broadcast media.   This study, will also enable the researcher to known if the news managers, News editors and Reporters (journalists) persistently carry out their gate – keeping roles and at the same time still carry out their watchdog roles.   In other words, whether they still maintain the ethics and laws of the profession or not or they are being influenced by the news sponsors and their money.   The study will also endeavour to find if the audience / public have it in mind that the news they read in newspapers and watch in these broadcast media are owned and are paid for by the sponsors since they are not usually mentioned during news broadcasting and information dissemination.                  
1.2       Statements of the Research Problems
Critics have identified distortion of news, imbalanced report and the growing tendency for the public not to believe the media news (lack of objectivity) as major problems inherent in Africa Independent Television and Nigerian Tribune for news and other information.   This is the key problems the researcher wishes to establish is this research work.   Objectivity as an ethical standard is one of the most pervasive in all of journalism. Objectivity in news gathering and presentation is the reporters’ aims and objectives.    
1.3       Objectives of the Study  
The core aims and objectives of this study is to assess the credibility of broadcast news in both Africa Independent Television and Nigerian Tribune since its partial commercialization brought the emergence of news commercialization.   Policy of commercialization is not for private and cooperate organizations to be stake holders in media organization but for such means to be sources of fund for the running of the activities of the media, for the fact that government subventions is sacredly less to keep the organizations afloat. Therefore, the standard set up on news commercialization is another means by which funds can be raised within the media, for the upkeep of the activities.   What is being argued here is that, the media should made commercial news known for the audience, for them to be aware that news they listened to at that point in time is sponsored, by an unidentified people.   What the researcher meant is that the paid news and news not paid should be distinguished.   Observations made are shown that there are limitations in gate keeping functions of the editor. “The gate keeper is any person or formally organized group directly involved in relaying or bans ferry information from one individual to another through any medium of mass communication.” Such person or individual has the ability to limit the information the public receive by editing the information, before it is disseminated.   The researcher equally wants to find out whether the above mentioned is practiced, for the fact that news paid for are edited as the sponsor wanted.    
1.4       Research Questions  
The following questions will be asked by the researcher:  
1.   What is the effect of news commercialization on the perceived “Brown envelope syndrome” and how has it affected the news credibility of these media?  
2.   Has news commercialization, deprived those who cannot afford the stipulated amount access to media?  
3.   Has the gate-keeping role being restricted because of news commercialization?  
4.   Do the audience know that the news they watch on AIT and read on Nigerian Tribune are paid for?    
1.5       Significance of the Study

The study of commercialization in media houses will assist the concept and to know its role in enhancing the success or failure of broadcasting industries.    
1.6       Purpose of the Study  
A lot has been said about commercialization on the contents of private media, however, little is known about ratifications and implications of the organization of this measure and how far it has affected or will affect the operation of the organization, their performances and fulfillment of their obligations and responsibility to the Nigerian public.  
1.7       Scope of the Study 
Although, the primary aims and objectives of the project are to examine the effect of commercialization on the content of private media, this can not be effectively talked without considering the demographic factor of AIT and Nigerian tribune staffs and sample number of the public that respond to the questionnaire of this study. Experience, education background, professional training, age, sex e. t. c must be considered before the distribution of research instruments.        
1.8       Limitations of the Study    
The study concentrates mostly on credibility and objectivity of news in Africa Independent Television and Nigerian Tribune. These factors will be linked up with the brown envelope syndrome amongst journalists and news editors. Time constraint has posed a lot of limitations to this work, inadequate finance of this project is another hindrance. This project is also limited to AIT and Nigerian Tribune where all findings would be generalized.
