BiffCo

BiffCo Enterprises (alternatively called "Biffco Enterprises"), also known as BiffCo (alternatively called "Biffco"), is a company founded by Biff Tannen after making millions betting on horse races with help of the Grays Sports Almanac in the "Biffhorrific" timeline (specifically alternate 1985), and an antagonistic faction in Back to the Future Part II.

Biff, back in 1955 when he was a teenage high school student, recieved the Gray's Sports Almanac from his older self from the year 2015 under the presumption that they are both distant "relatives". He told him that the book tells every sporting event until the end of the 20th century. Old Biff told him that all he had to do is bet on the winners and he would never lose, and so young Biff took his word and betted on winning race horses and became a millionaire overnight on his 21st birthday and was ironnically named as "The Luckiest Man on Earth" the local Hill Valley Telegraph newspaper. But before young Biff proceeds with this "gift" the elderly Biff has given him, he warned his teenage self to keep it hidden and away from anyone (in this case, Marty Mcfly and Doc Brown) would threaten to expose the Almanac even by asking questions about it, and if that ever happens, he must dispose of them (even it means murdering them). He soon used his money and built his namesake industrial empire BiffCo which first started out as a nuclear power plant, while he enjoys his newfound fortune in everything including chasing the world's beautiful women, owning a yacht he named "Monkey Business", and owning his own namesake mansion "Tannen Manor" somewhere in California, possibly near his home of Hill Valley. He invested in toxic waste reclamation and in other heavy polluting industries with the company. Biff's position in the company gave him great influence over political leaders and law enforcement. This in turn given him control over his now dystopian hometown of Hill Valley and legalized gambling which later lead to build his own "luxurious" hotel casino      in replacement of the old   Hill Valley Courthouse .

BiffCo Realty, real estate company that is a part of BiffCo Enterprises, owned Lyon Estates : a line under the statues of lions said that Lyon Estates was "a proud member of the BiffCo family".

The BiffCo no longer existed after Marty and Doc Brown undo the changes made by the old Biff and restore their original reality by destroying the Gray's Sports Almanac.

Trivia

 * BiffCo Enterprises' alias "BiffCo" is named after the music production and songwriting team Biffco.
 * Biffco built and owned the Toxic Waste Reclamation Plant N°7, a toxic waste reclamation plant.
 * According to number of the plant, there are about to a minimum of 7 reclamation plants in Hill Valley.
 * The constuction of Courthouse Square in 2015 began when the 1985A scenes in Courthouse Square were shot. So, the set of 1985A hid the set of 2015 : the Reclamation Plant hid the blue building of 2015.
 * The elaborate set for Courthouse Square in the 1985A "Biffhorrific" timeline is visible on screen for only 60 seconds in Back to the Future Part II, between the time Marty steps across the remains of the welcome sign, and notices the Biff Tannen Museum. Many of the details were not evident in the film, but a set of photos on the Blu-ray edition of the trilogy show some location around Courthouse Square in 1985A.
