"Mobile ownership in all of the four surveys [in Ghana, Nothern Nigeria, Senegal and Tanzania] was around 90%, making the mobile phone the most widely owned device media device, both used as a media carrier (radio) and a media in its own right (Internet, SMS) [...] Radio remains the dominant medium for obtaining news and information and only in Ghana (where electricity access is wider) does TV come close to the percentage of those listening to radio. In each of the countries examined, the media has been liberalized and the radio and TV audiences are fragmented so that only a relatively small number of players reach over 25% of the audience [...] As the continent’s most owned device, the mobile phone is used most regularly for: voice calls; radio; SMS; Internet and Social Media. Between a fifth and a third of all those surveyed used the Internet on a daily basis [...] Between 14-27% of all those surveyed used social media and the dominant platform is Facebook [...] Radio and TV channels scored most highly in terms of those surveyed trusting the health information they heard on saw on them. The level of trust in these channels in Senegal was significantly lower than in the other countries." (Summary, page 5-9)
