je and .gg first appeared on the Internet in 1996 after Jon Postel agreed with Nigel Roberts of Island Networks to add four codes (GG and JE, and IM and AC) to the IANA list of TLDs.
net.nf parallel the .com and .net TLDs, while some of the others appear to be based on proposed new TLDs from the late 1990s which were never implemented (other than the eventual use of .info).
In 1996-1998 he programmed and co-designed the Internet political art project namespace, which was designed to unstrain the Internet from special interest's control and expanded the artificial limitation of TLDs imposed on the Internet users by Network Solutions and IANA.
