The name North Star is taken from U.S. Route 219, the North Star Way, which runs through the District.  That name for the highway has since fallen out of favor.  The district encompasses approximately 102 square miles.  According to 2000 federal census data, it serves a resident population of 9,519.

The Tycoon (TV series): The Tycoon is a 32-episode American sitcom television series broadcast by ABC.  It starred Walter Brennan as the fictitious businessman Walter Andrews, similar to his birth name of Walter Andrew Brennan.  As chairman of the board of the Thunder Corporation that he founded but no longer actively runs, Brennan plays an eccentric and cantankerous millionaire (when such persons were much fewer in number) with a common touch who helps promising persons in need.  The series aired with new episodes at 9 p.m. Eastern time Tuesday from September 15, 1964, until April 27, 1965.  It continued in reruns until September 7, 1965.  The program did not develop sufficient audience, presumably because viewers may have preferred the versatile Brennan as the bucolic Grandpa Amos McCoy in his 1957-1963 ABC and CBS sitcom "The Real McCoys".  Oddly, "The Tycoon" has the same name as an episode of "The Real McCoys" also called "The Tycoon," which aired four years earlier on August 23, 1960.

Academy Honorary Award: The Academy Honorary Award – instituted in 1948 for the 21st Academy Awards (previously called the Special Award, which was first presented in early 1929) – is given annually by the Board of Governors of the Academy of Motion Picture Arts and Sciences (AMPAS) to celebrate motion picture achievements that are not covered by existing Academy Awards, although prior winners of competitive Academy Awards are not excluded from receiving the Honorary Award.  Unless otherwise specified, Honorary Award recipients receive the same gold Oscar statuettes received by winners of the competitive Academy Awards.  Unlike the Special Achievement Award instituted in 1972 (and discontinued in 1995), those on whom the Academy confers its Honorary Award do not have to meet "the Academy's eligibility year and deadline requirements."  Like the Special Achievement Award, the Special Award and Honorary Award have been used to reward significant achievements of the year that did not fit in existing categories, subsequently leading the Academy to establish several new categories, and to honor exceptional career achievements, contributions to the motion picture industry, and service to the Academy.  The Academy Honorary Award is often awarded in preference to those with noted achievements in motion pictures who have nevertheless never won an Academy Award.  Thus, many of its recipients are Classic Hollywood stars, such as Lillian Gish, Barbara Stanwyck, Kirk Douglas, and Lauren Bacall.
