As a result of the removal of the BitKeeper license, Linus Torvalds decided to write his own DVCS, called git, because he thought none of the existing open-source DVCSs were suitable for his particular needs as a kernel maintainer (which was why he had adopted BitKeeper in the first place). A number of other developers quickly jumped in and helped him, and git over time grew from a relatively simple "stupid content tracker" (on which some developers developed "porcelain" extensions) into the sophisticated and powerful DVCS that it is today. Torvalds no longer maintains git himself, however; it has been maintained by Junio Hamano for many years, and has continued receiving contributions from many developers.
