The first seed of ATCI was planted in 1983 when a group of computer vendors came together
to organize an exhibition to promote local computer businesses. The show, IT Trade, has
grown to be the key Information Technology Industry event in the country.
inspired the participants toestablish the Association of Thai Computer Industry (ATCI) which
proceeded to grow in both size and scope. To respond to the growth, in 1998 ATCI adopted
a new charter extending membership to any company that sees information processing
as core to its business, including manufacturers and information service providers. The
expanded member categories better reflects the dynamism of the information industry.
In line with the convergence of Information Technology and Communication Technology
ATCI was renamed to the Association of Thai ICT Industry in 2005.
