As part of the BBC's second African Dream series, Emelda Mwamanga talks about the highs and lows of the competitive magazine industry.
Noticing a gap in the Tanzanian market, she started Bang! - a lifestyle magazine. After some initial stumbling blocks, the magazine's circulation has grown and Mrs Mwamanga's sights are now set on even bigger things.
Alex Jakana reports.
African Dream is broadcast on the BBC Focus on Africa radio programme every Thursday afternoon and on BBC World News throughout the day on Fridays.
