<Li> The film shows Marty putting on Nike "Air Mag" tennis shoes with automatic shoelaces . Nike released a version of their Hyperdunk Supreme shoes, which appear similar to Marty's, in July 2008 . Fans dubbed them the Air McFly . In April 2009, they filed the patent for self - lacing shoes, and their design bears a resemblance to those worn by Marty in the film . In 2010, a fan named Blake Bevin created shoes that tie themselves . Though Nike had made very limited quantity of Air Mags in the same style as the movie, they stated in September 2011 that their consumer - line MAG line of shoes would not feature the self - lacing feature shown in it . Tinker Hatfield, one of the shoe's designers, indicated in 2014 that they would introduce shoes with power - lacing technology the following year, 2015 . In March 2016, Nike unveiled the HyperAdapt 1.0 shoe, which is a consumer - market model of the Air Mag and features the same self - lacing technology they used for the commemorative Air Mags, and are expected to start selling in late 2016 . </Li> <Li> The concept of the hoverboard--a skateboard that can float off the ground--has been explored by various groups since the release of the film . Attempts similar to hoverboats, which blast air at the ground, have been demonstrated, with a 2015 record distance of 275 meters . A different type is the MagBoard, developed by researchers at the Paris Diderot University . It uses a large superconductor plate on the bottom cooled with liquid nitrogen as to achieve the Meissner effect and allow it to float over a special track; it was shown capable of carrying the weight of a human in its practical demonstration . However, the requirement to run the superconductor at higher, more ambient temperatures prevents this from becoming practical . In March 2014, a company named HUVr Tech purportedly demonstrated a working hoverboard along with several celebrities including Lloyd, though this shortly was revealed as a hoax created by the website Funny or Die . self - balancing' hoverboards' became popular in 2015 even though they do not hover above the ground . </Li> <P> In the 2015 scene, the film imagines the Chicago Cubs winning the 2015 World Series against the fictional Miami - based Gators, referencing the Cubs' longstanding failure to win a championship . In the actual 2015 season, the Cubs qualified for the postseason, their first postseason appearance since 2008, but the Cubs lost the National League Championship Series (not the World Series) to the New York Mets on October 21, 2015, which coincidentally was the same day as "Back to the Future Day," the day Marty McFly arrived in 2015 in the film . Despite losing in 2015, one year later the Cubs did win the 2016 World Series against the Cleveland Indians . In the real 2015 World Series, the Kansas City Royals defeated the Mets to win their first World Series championship since 1985, the same year from which Marty and Doc time traveled in the film . As for the fictional Miami Gators, when the film was made Florida did not yet have a Major League Baseball team, but the state has since gained two franchises: the Florida Marlins (now the Miami Marlins) in 1993 and the Tampa Bay Devil Rays (now the Tampa Bay Rays) in 1998 . Neither qualified for the postseason in 2015 . </P> <P> The film was released to theaters in North America on Wednesday, November 22, 1989, the day before Thanksgiving . It grossed a total of $27.8 million over Friday to Sunday, and $43 million across the five - day holiday opening . On the following weekend, it had a drop of 56 percent, earning $12.1 million, but remained at #1 . Its total gross was $118.5 million in the United States and $213 million overseas, for a total of $331 million worldwide, ranking as 1989's sixth-most successful film domestically and the third-most worldwide--behind Indiana Jones and the Last Crusade and Batman . However, this was still short of the first film's gross . Part III, which Universal released only six months later, experienced a similar drop . </P>

When did the cubs win in back to the future
