Answer: Babylon 5
Babylon 5 was an American television series and sci-fi space opera in the 23rd century. The exhibition moved from 1993 to 1998 with a total of 110 episodes and six TV movies. Babylon 5 became highly famous for its development of complex storylines involving religious conflict, economic conflicts, racial tensions and more, all woven together with excellent writing and character development.
In addition to making a favor to the sci-fi television genre by demonstrating how mature and developed a sci-fi story could be, Babylon 5 was also a pioneer for the use of computer-generated TV models.
The trend then was to use real models against different backgrounds to create illusion of things like space travel ̵1; the USS Enterprise 1701-D, from Star Trek: Next Generation for example, was simply a trio of Large and well-kept models of the ship hanged in front of a screen. In Babylon 5, however, the space station (the nexus of the many history of the show bows) and the ships that visited it all were done with the help of computers.
In addition to using CGI as the primary method of its visual effects and being the first television program to use virtual sets, it is remarkable that the computer crew behind the models invested a significant amount of energy to create computer models that followed the laws of physics to create a realistic experience for the viewer.
