This week’s Digital Planet is something of a celebration, it's 20 years since the BBC World Service launched the programme. Originally entitled ‘Go Digital’, the programme has always been innovative. It was the first radio programme to generate digital video, and also launched podcasting. We look back over two decades at how technological innovation has changed global society. The programme began in an era where smartphones didn’t exist and the social media we know today had yet to be invented.

The programme is presented by Gareth Mitchell with expert commentary from Tracey Logan, Alfred Hermida, Ghislaine Boddington, and the programme’s longest-serving contributor Bill Thompson.
