The first university radio in the world appeared on 19th November 1923 in Argentina - it was called the Radio Universidad. Since then, university radios followed up the evolutionary course of the common radio over the decades, representing the interests of the academic community. Such as web educational and training radio projects that emerged in the late 90´s, the online broadcasters, brought up in the university departments, and the university radios began to supply a range of services and applications that did not exist till then. Unlike conventional radio, Internet radio immediately sparked the interest of the broadcasting companies, once it did not impose limits on the listener´s geographical range, nor on the exclusive audio format programming. These radios have not delayed in employing the technological resources of web radio, fact that can be sustained by the quantitative growth of online platforms, through which people can have access to the ordinary programming in real time by means of a great variety of devices connected to the Internet. This investigation considered it important to analyze the educational potentialities of web radios in the Spanish and Portuguese academic universe. For that purpose, we made a selection of some experiments using Perona´s selection criteria of "Modalities of Educational Radio". In Portugal, the study was deeper and wider so that we were able to identify the differences and particularities of the six university radios available on the Web, described in more detail on the Rádio Universitária do Minho case study.
