Hill Valley's Courthouse Square in 2015.

2015 is a year in the 21st century.

On October 21, 2015, one hour before his past self would arrive with Marty McFly and Jennifer Parker, Emmett Brown prevented the hydrator, Nike MAG, hoverboard, and Mr. Fusion from being available by 2015 to prevent a nuclear holocaust in 2045. Because of this, most things that they originally witnessed in 2015 never existed. The only technology that was shown to exist in the new timeline was tablet computers, the internet, self tracking video cameras, and digital versions of newspapers.

Original timeline

By this time in history, technology had progressed as much during the 30 years since 1985 as it had during the previous 30 years from 1955 to 1985. Electronics were in virtually everything from clothing to garbage cans to make them move, talk and/or make electronic noises.

Flying cars, once they were invented and perfected, had become so common that drivers no longer needed roads — except perhaps for short journeys. Skyways dominated the skies of central California and eventually the entire world. Cultural influences from other countries, particularly Japan, were more often seen in food and clothing.

Life was lived at a quicker pace than before, in evidence by the speed that people walked down the street, the time it took to cook dinner, and the swiftness of court trials.

Hill Valley underwent a period of gentrification, or revitalization of its downtown. With an increased concern for the environment, the Courthouse Square was landscaped with a large artificial lake (with the surrounding road having NO LANDING markings applied to dissuade drivers of flying cars from bringing their vehicles down near the lake), and businesses were brought back with the construction of an underground Courthouse Mall.

New organizations


  • Friday, October 16 or earlier: Holomax Jaws 19 debuts at the theater: "This time, it's really really personal."
  • Wednesday, October 21:
  • Thursday, October 22: Originally, Marty Jr. is tried, sentenced and convicted to 15 years in the state penetentary due to a robbery. After Marty changes history to save Marty Jr., Griff is sent to jail for wrecking the Courthouse.
  • Friday, October 23: Queen Diana visits Washington, D.C. according to the October 22, 2015 issue of USA Today (of course, in reality, the princess died in 1997).
  • Monday, October 26: Doc and Einstein arrive in the future (assuming they went exactly 30 years ahead from October 26, 1985).
  • Wednesday, October 28: Before Marty alters the course of future events, his daughter Marlene attempts to break her brother out of prison. She is sentenced to 20 years in jail.
  • Dates unknown: Doc spends an unknown amount of time in 2015 and later. While he is there, he outfits the time machine with a Mr. Fusion and a hover conversion, undergoes personal rejuvenation surgery, and learns as much as he can about Marty Jr.'s meeting with Griff on October 21. Doc also places Einstein in a suspended animation kennel. Eventually, Doc leaves for 1985 to pick up Marty and Jennifer.
    • After being accidentally sent to 1885 and settling on the Old West, Doc managed to create a time travelling train, and went to 2015 (or beyond) to have it hover converted.

Behind the scenes

  • Wednesday, October 7: The original date that Marty, Jennifer and Doc would travel to as opposed to the 21st.

Real world



  1. When asking Doc why his 1931 counterpart couldn't have invented a hoverboard, Doc responds that they wouldn't be invented for another 84 years.


  • It is now 2015 in real life and there are no widely-produced flying cars, auto-adjusting and auto-drying jackets, power-lacing shoes, etc.
  • The basic concept of watching multiple channels at once – as Marty Jr. does – technically exists, with modern televisions offering picture-in-picture functionality and various satellite TV packages offering overviews of certain groups of channels based on genre – like sports or family channels – which can be viewed all at once. Some smart TVs also already support simple voice commands which allow the viewer to control functions such as turning the TV on and off, changing channels, accessing apps, and navigating the web.
  • Almost all of the billboards shown around Courthouse Square are holographic billboards, which are yet to be widely adopted since the technology required to produce such displays is still in its infancy.
  • Flying cars may be possible, as Massachusetts-based company Terrafugia has invented the Transition, a car with collapsible wings capable of flight, which are expected to be marketed in 2015. Another car, the TF-X, is planned for release in 2021.
