In its “Big Data Challenge,” Telecom Italia pooled data between November 2013 to December 2013 with partners from various Italian industries (local news, automobile, energy and weather) into one aggregated, geo-referenced dataset for participants to use for the competition.
During the contest, the data for Telecom Italia's challenge was available in batches and through an API, and contained millions of call data records, energy consumption records, tweets, and weather data points. Recently, the dataset used for the contest was made open to the public [via their website.](http://theodi.fbk.eu/openbigdata/) This data was released under the The Open Database License (ODbL) available in its raw form or through an API.
Telecom Italia's Big Data Challenge focused on creating and developing innovative technological ideas in the field of Big Data, in order to spur innovation in this sector and improves the lives of individuals, companies and communtities.
