TAGnet was founded by a forward looking ASI member named Sean Carney in 1995. At the time, Sean worked in the Silicon Valley for a company called Excite. His desire was to utilize the Internet to share the "Good News." 

TAGnet's early days were marked by a creating a hosting service tailored to Seventh-day Adventist churches, schools and ministries. At the time, hosting was not well understood by those wanting to enter the world wide web, and TAGnet was able to provide a unique service that assisted those with a burden of using the Internet as a ministry platform. TAGnet was also involved in a number of specific projects on the web, most notably working with Adventist-laymen Services and Industries (ASI) and the General Conference of Seventh-day Adventists on an initiative called Sow One Billion. The goal of this initiative was to distribute 1 Billion Bible study invitation cards globally. TAGnet's role in this initiative was to create a web portal for a global audience that complimented the invitation cards and allowed visitors to take Bible studies on-line. Over 44 language Bible studies were offered from a variety of Seventh-day Adventist ministries, and TAGnet was the facilitating ministry that got it all up and running. 

In 2005, TAGnet came to a point in its ministry where it needed to refocus on its core mission. Hosting had become a commodity, and there was clear need for cloud-based software that was less technically challenging and more user-friendly for someone without technical training. TAGnet joined a family of companies overseen by Hart Research Center, and re-focused its efforts on creating a cloud-based software application platform targeted at Seventh-day Adventist churches and schools. The result was netAdventist.

NetAdventist was first introduced in North America in early 2006, with excellent results. Thousands of sites were created, and users settled in to using the new software platform, especially enjoying it's content-sharing capabilities. Versions 1.0 and 2.0 quickly evolved, and as international demand for netAdventist grew, the TAGnet development team made the decision to re-build the platform from the ground up to accommodate user feedback, internationalize the software, and simplify the architecture and platform upkeep. The resulting product, netAdventist 3.0, is now deployed on 5 continents in 5 languages, with a user base of over 30,000. 

TAGnet gifted the netAdventist platform and its oversight to the General Conference of Seventh-day Adventists in October of 2007. A new office, the Office of Global Software and Technology, was created to handle oversight of the software, which has continued software development and marketing of the product to the global denomination. Right around the time of the gifting of the software, a new company was formed from the existing TAGnet staff called netAserve, with the express goal of furthering development and providing service for the netAdventist platform. 

Today, TAGnet's primary role as a ministry is to further encourage development and use of the netAdventist platform. One of the ways we accomplish this is through the netPrize award, which is given to developers who write new functionality for the netAdventist platform. $37,500 in cash prizes was awarded at the annual GIEN (Global Internet Evangelism Network) conference to programmers on three different continents who contributed new software extensions to the netAdventist platform. TAGnet will continue to look at new projects that utilize technology to further the Great Commission. We find that technology is an excellent way to "Go into all the world!"
