Developed in 2014 by Mid-Wisconsin Federated Library System as Technology Day, Winnefox Library System joined forces with MWFLS as a co-sponsor in 2015.
In 2016, Winnefox collaborated with Outagamie Waupaca Library System, Manitowoc-Calumet Library System, and the SEWI group of library systems (Arrowhead, Bridges, Eastern Shores, Kenosha County, Lakeshores, Mid-Wisconsin, and Milwaukee County) to provide two Tech Day workshops held in Fond du Lac and Franklin.
By 2017, South Central Library System and Nicolet Federated Library System joined as co-sponsors, and Tech Days expanded to a series of three workshops held on consecutive days in Fitchburg, New London, and Franklin.
Starting In 2018 and continuing through 2019, Tech Days broadened into an East series and a West series (co-sponsored by IFLS Library System, Northern Waters Library Service, Winding Rivers Library System, and Wisconsin Valley Library Service) to provide two sets of three workshops at six regional locations around the state. Both series also gained sponsorship from the Wisconsin Department of Public Instruction (DPI), Public Library Development Team, with funding support from the Institute of Museum and Library Services.
Due to the coronavirus and COVID-19 pandemic in 2020 and 2021, Tech Days transformed from a workshop series into a webinar series.
