Airtime is a  radio management application for remote broadcast automation (via web-based scheduler), and program exchange between radio stations. Airtime is being developed and released as free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 3 or any later.
The initial concept for Airtime, originally named LiveSupport, and then Campcaster was developed in 2003 by Micz Flor, a German new-media developer. The concept was further developed by Ákos Maróy, a software developer and then-member of Tilos Radio, Robert Klajn, a radio producer at Radio B92, and Douglas Arellanes and Sava Tatić from the Media Development Loan Fund (MDLF). The initial development was financed from a grant from the Open Society Institute's Information Program, through its ICT Toolsets initiative. The development was originally coordinated by MDLF through its Campware.org initiative, now spun off as the independent not-for-profit organisation Sourcefabric.
In January 2011, Sourcefabric announced a rewrite of Campcaster, beginning with the 1.6 beta release. The new product, known as Airtime, replaced the C++ scheduler of Campcaster with Liquidsoap, and includes a drag and drop web interface based on jQuery.
Airtime 1.8.1 was released on May 3, 2011 following up on releases 1.7 and 1.8 in April. The ability to edit shows was introduced, show repeat and rebroadcast made possible, and the calendar improved with reported loading times five to eight times faster. Airtime’s default output stream became Ogg, rather than MP3.
Airtime 1.8.2 was released on June 14, 2011 with improvements to installation, upgrade, file upload limit and the interface.
Airtime 1.9 was released on August 10, 2011 with a new file storage system that allowed users to set 'watch' folders, to synchronise files and to browse their audio archives. Also added were SHOUTcast support, a one line Ubuntu install command and improved front-end widgets. 1.9.4 was released on September 27 with DEB packages for Ubuntu and Debian.
On 5 June 2012, Airtime 2.1 added live stream rebroadcasting from remote sources and on-the-fly editing of live shows in a revised Now Playing interface. A bugfix update 2.1.2 was released on June 18.
Airtime 2.2 added smart blocks, live assist features and new streaming capabilities and was released on 29 October.
In September 2011, Airtime was nominated as one of five finalists in the Packt Open Source Awards 2011 in the Multimedia category. In 2012, Airtime won the Guardian Awards for Digital Innovation in the category Best Use of Technology for Social Change.
