Each episode is introduced by the hosts, Spencer Kelly and Lara Lewington, and features reports about technology developments all over the world by a group of BBC contributors.

BBC World Service used to broadcast a weekly sister radio show, Digital Planet, which, for a time, shared the same name.

[5] Further local versions are due to launch from Autumn 2018, including Click Tamil in October 2018, with the aim of having the show broadcast in up to 20 languages.

[6] The show started as Click Online in April 2000, hosted by Stephen Cole, and featured reports focused on the rise of the Internet and related technologies.

The show bought control of a botnet of some 22,000 infected computers (for "a few thousand dollars")[10] from a Russian hacker, and used it to send spam to an email address set up for the experiment and to perform a Distributed Denial of Service (DDoS) attack on a website set up by Prev-X (an internet security company that provided technical support for the show).

[11] After the programme was made the computers on the botnet were sent a piece of software to remove the malware and a warning was sent to them telling the users what had happened and that they were vulnerable.

[15] Click rebutted criticisms by stating in its Twitter posts that: We would not put out a show like this one without having taken legal advice.In addition to presenters Kelly and Lewington, reporters include LJ Rich, Paul Carter, Marc Cieslak, Zoe Kleinman, Nick Kwek, Shiona McCallum,[16] Alasdair Keane [17] and Kitty Knowles.

Previous presenters of the show have included Stephen Cole who left the BBC to work for Al Jazeera International.
