Net Jet is a Windows PC-based game system introduced by Hasbro (under the Tiger Electronics brand) in 2007.
The Net Jet controller is plugged into the USB port in a computer and automatically started up.
The Net Jet makes itself plug n play by containing a small bit of firmware in the controller.
When plugged in, a virtual CD-ROM image (400K in size) would automatically mount, then proceed to download and install its software via the Internet so to display a menu selection screen.
Later on, the demo key was replaced in branded bundled with some of the Net Jet's marquee titles, such as Transformers Battle Universe or Bubble Bonanza, for example.
The keys however permanently "remember" which three choice games the player selected via a 1K embedded EEPROM IC.
Many of these titles were also available on other web gaming portals but had been retooled to support Net Jet specific button inputs.
