Squeezed into some 60 pages is a review of how digitisation is impacting on media in Southern Africa, and especially how the new digi-scape is impacting on state-owned broadcasters. It's been produced for distribution at the 13th Highway Africa conference to a mass of influential people in journalism and journalism education.

Overall, Africa’s mobile market has probably been the fastest growing of any region in the world over the past five years, and mobile access has grown twice as rapidly as the global average.

It took the African continent 100 years to accumulate 28 million fixed lines – an average access rate of 3 per 100 inhabitants – but this was overtaken by mobile connections in 2001, and with 137 million mobile subscribers in 2005 mobiles outnumbered fixed lines by more than five to one.

A rude awakening in the news that Vodacom is becoming a media company.

It's not about the firm's distribution of a bouquet of other people's TV via 3G (and in future DVB-H). It's not even about content as such.
