The dataset contains data on prices, supported platforms, features, development history and popularity of software selected in four license categories (Proprietary, GPL, BSD, Dual licenses) across six categories (Word processors, Back-up software, database software, graphical applications, instant messengers and web browser). The data was collected from 4 main sources so as to ensure representativity of the software population in five main software marketing /distribution categories (shareware, freeware, open source and shelfware). 84 software were surveyed in total, half of them proprietary, half of them open-source, and information about 15 aspects of each software was collected. About 1260 data-points were thus collected in total over two months, two weeks being devoted to the development of a data collection methodology. The ESRC Centre for Competition Policy (CCP) at the University of East Anglia (UEA) undertakes interdisciplinary research into competition policy and regulation that has real-world policy relevance without compromising academic rigour. It prides itself on the interdisciplinary nature of the research and the members are drawn from a range of disciplines, including economics, law, business and political science. The Centre was established in September 2004, building on the pre-existing Centre for Competition and Regulation (CCR), with a grant from the ESRC (Economic and Social Research Council). It currently boasts a total of 26 faculty members (including the Director and a Political Science Mentor), 4 full- and part-time researchers and 23 PhD students.
