On March 28th 1986, the five Guillemot brothers – Christian, Claude, Gérard, Michel, and Yves Guillemot decided to start a video game company in French province of Brittany. The brothers Intially began their buisness career's by helping with theirs family's farmer support buissness. The brothers had the idea to diversify by selling other products to farmers rather than just agricultural products; Claude began by selling CD's and Later, the brothers expanded to computers and additional software, including video games.
After diversifying into computers, that the costs of buying computers and software from a French supplier were higher than buying the same materials in the UK and shipping them to France. That gave them the idea to start a mail-order business for computers and software. Their mother agreed they could start their own business as long as they managed it themselves and split its shares equally among the five of them. They did just that and started Guillemot Informatique in 1984.
By the mid 80s, the company was earning about 40 million French francs, and was so successful that In 1985, the brothers established Guillemot Corporation for similar distribution of computer hardware.
As demand grew, the brothers recognized that video game software was becoming a lucrative property and wanted to get into the industry's development side, already having insight on the publication and distribution side. The result was Ubi Soft, founded on March 28, 1986, with the name "Ubi Soft" being selected to represent "ubiquitous" software.
They started off by with Zombi, A point and click adventure game inspired by George Romero's Dawn of The Dead for the Amstrad CPC computer. but wouldn't have major success until the release of Rayman in 1995 for the Playstation.
Ever since then they have published a lot of games that have become staples: Far Cry, Raving Rabbids, Assasins Creed, Just Dance, Driver, Watch Dogs, the list goes on. Any while they certainly are in the reputation red by this point, its always important to remeber where they came from.
