By 1985, Hill Valley had experienced growth in its surrounding neighborhoods and suburbs. Downtown was less vibrant as commercial interests moved out around the Twin Pines Mall area, on the former site of Twin Pines Ranch, as well as former residential areas of town (see John F. Kennedy Drive). A community known as Hilldale was beginning construction just east of the Eastwood Ravine.
By 1985, there was an increase in civil rights, cultural upheaval and usage of electronic computing.
After old Biff Tannen disrupted history by traveling back in time from 2015 in Dr. Emmett Brown's stolen DeLorean time machine to 1955 to give his younger self the Grays Sports Almanac, this year became the nightmarish ABC timeline 1985A.
