Ultranet

The Ultranet is a virtual reality Internet-type thing. Users can plug a cord from a computer into a port in their neck to be instantly transported to the Ultranet.

History
Zia Simpson used the Ultranet a lot, prompting Lisa to use it to find her. She goes onto and instantly gets a list of people trying to befriend her, including Marcia Princess and Nelson Muntz. She then goes to find and uses that to search for Zia. When she finds Zia's room on the Ultranet, she sees that Zia really does look up to her, while a party is going on next door.

Behind the Laughter
The Ultranet is very similar to and may draw inspiration from Futurama's Internet.
