ETDZ has legally become operational with the decision of the Council of Ministers on the "Determination of Some Areas as Technology Development Zones, No. 2003/5390" published in the Official Gazette on 10 April 2003. ETDZ was firstly deployed on an area of 510 decares with two separate pyramid buildings in Eskişehir Organized Industrial Zone. In line with the increasing demand of entrepreneurs, Yazılımkule was built and put into service in 2008. With the decision of the Council of Ministers published in the Official Gazette numbered 27302 on 28 July 2009, the immovables in Anadolu University Yunus Emre Campus and Eskişehir Osmangazi University (ESOGÜ) Meşelik Campus have been encompassed in ETDZ by naming respectively “ETDZ Anadolu Technopark Additional Area” and “ETDZ Osmangazi Technopark Additional Area". As a result of the efforts made to ensure that the physical areas can meet the needs of the entrepreneurs, a new technopark building was built on the Osmangazi University Meşelik campus and became operational at the beginning of 2017. The establishment of Eskişehir Technology Development Zone is a step taken as a result of the importance given by ECI to modern technology and the development of this technology with local resources, in line with the examples mentioned above. With the Zone, an exemplary working environment for university-industry cooperation has been created with the contribution of the scientific synergy created by Anadolu and Osmangazi Universities in the city. In this direction, the management company of Eskişehir Technology Development Zone – Anadolu Technology Research Park Company (ATAP Inc.) was established on 18 September 1990 with the support of the United Nations Fund for Science and Technology for Development. ATAP Inc. is the first TDZ management company established in Turkey.
