SLI was created and introduced by 3DFX before they got acquired by NVidia...Had a Voodoo card back in 1998, was following the infos about SLI...never heard of Big Bang one

3dfx Interactive was a company that specialized in the manufacturing of cutting-edge 3D graphics processing units and, later, graphics cards. After dominating the field for several years in the late 1990s, by the end of 2000 it underwent one of the most high-profile demises in the history of the PC industry. It was headquartered in San Jose, California until, on the verge of bankruptcy, many of its intellectual assets (and many employees) were acquired by its rival, Nvidia Corporation. 3dfx Interactive filed for bankruptcy on October 15, 2002.

SLI

The Voodoo2 introduced Scan-Line Interleave (SLI) to the gaming market. In SLI mode, two Voodoo2 boards were connected together, each drawing half the scan lines of the screen. For the price of a second Voodoo2 board, users could essentially double their 3D throughput. A welcome result of SLI mode was an increase in the maximum resolution supported, now up to 1024×768. Despite the high cost and inconvenience of using three separate graphics cards (two Voodoo 2 SLI plus the general purpose 2D graphics adapter), the Voodoo2 SLI scheme was the pinnacle of gaming performance at the time[citation needed].

SLI capability was not offered in subsequent 3dfx board designs, although the technology would be later used to link the VSA-100 chips on the Voodoo 5.

Having since acquired 3dfx, Nvidia in 2004 reintroduced the SLI brand (now for Scalable Link Interface) in their GeForce 6 Series. ATI Technologies has also since introduced its own multi-chip implementation, dubbed "CrossFire". Although Scalable Link Interface and Crossfire operate on the original SLI principle, the algorithms used are now totally different.
