Some CD-i titles have a very long history, like with Zenith on CD-i. Philips has been in the computer business for a long time. They have developed Personal Computers since the early eighties with the P2000 series. In these days there were lots of third party software houses who were contractually developing software exclusively for Philips and their Home PC systems. One of them was Radarsoft: A small company which was flourishing in the late eighties with products like ‘Dynamic Desk’ and ‘Dynamic Environment’.
It was a long way from a concept design to any playable content.These products were delivered with all common Philips PC’s around (exclusively for Philips). When Philips shut down their PC business in the early ninetees, there was still a rolling contract with Radarsoft. With CD-i just around the corner, Radarsoft was offered to create a full funded cd-I title for Philips. Year: 1992. Apparently Radarsoft was given the free world to deliver their own original CD-i title. The project was run by only one person, accompanied with some technical help now and then by two colleagues.
In the end, Zenith appeared to be one of the most fun and most original base-case CD-i titles ever.
