The world in general is in an information age. Decision making now is based on large volumes of data. The computer has come to stay as the fastest and most efficient means of processing data. The micro-computer in particular has been enjoying wide acceptance. In Nigeria, it has become so popular that even very large organizations that generate large volumes of data are switching to it due to the fact that on the whole, it is less cumbersome. Because of the growing popularity of microcomputers in Nigeria, many computer marketing firms have sprouted up and more are being established. Even the great number of computer companies in existence to date can not satisfy the potential computer needs of the Nigerian market. However, the results obtained from this research have shown that the computer market in Nigeria is yet to stabilize as respondents could not tell. From the same research, it was also gathered that the computer market in Nigeria has a very bright future. The purpose of this research is to assess the application of marketing strategies and policies in the marketing of micro computers in Nigeria with the intent of proposing strategies that will lead to an effective manipulation of the necessary resources for the achievement of efficient and effective services to the market. To achieve this aim, A-Z Computer World Ltd. has been chosen as a case study because it possesses some interesting characteristics from which inferences can be drawn. In addition, forty questionnaires were distributed and ten (10) were returned. Also secondary data source as well as observations and measurements of existing situations have been used to obtain information. The findings show that feasible marketing strategies and policies have been developed but the problem lies in the implementation which is a result of a number of constraints prominent among which is finance. Competition was hardly mentioned because though it seems there is proliferation of computer marketing firms, they are hardly enough to satisfy the needs of the market. The problem is that of over-concentration in a particular area - Lagos. This study proposes appropriate measures to be taken to ensure adequate utilization of market potentials and satisfaction of existing or actual market. Possible solutions to the problems have been advanced.
