2015 is a year in the 21st century.
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.
In Back to the Future Part II, while Doc Brown (dad of Jules and Verne Brown, husband of Clara Clayton Brown) takes care of an unconsious Jennifer Parker, Marty McFly lands into the water after using a hoverboard during the chase, managing to escape from Griff Tannen and his gang, and as a result, they crash into the courthouse and end up in jail, thus preventing the robbery for which Marty Jr. would have been jailed.
It should be noted however that 2015 encountered by the DeLorean is presented as only one possible future. Some events such as Marty getting into an automobile accident in 1985 as well as him being fired from his office job in 2015 are explicitly shown to have been averted by the end of Back to the Future Part III. Whether the rest of 2015 was altered as a result remains to be seen. It is also possible that Doc and Marty's activities in 1885 had long-term effects that were still too subtle to be noticed when Marty returned to 1985, but which fanned out and caused significant historical changes between 1985 and 2015. Examples must remain purely hypothetical, but one could for instance imagine that the great-grandmother and great-grandfather of the person who would invent anti-gravity devices in the 1990s met on a train in 1886. However, since the locomotive that would pull said train was stolen and destroyed by Marty and Doc already one year earlier, an entire family line faded from history. The inventor of anti-gravity devices was never born. Such hypothetical scenarios could explain why we are currently living in a 2015 without hoverboards and flying cars.

- 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.
