Douglas Harper's Etymology Dictionary
abbreviation of District of Columbia, apparently not widely used before 1820, but eventually it became necessary to distinguish the place from the many other "Washingtons" in America. The city and the district were named in 1791 (at first known as Territory of Columbia; the territory was organized as a "district" in 1801), but the towns within it (Washington, Georgetown, Alexandria) remained separate municipalities and at one time all took D.C. The district was effectively organized as a unitary municipality in 1871.
abbreviation of direct current, attested from 1898.
D.C. is an American television series that premiered and ended in April 2000 on The WB Network.
Mason Scott ( Gabriel Olds), a young man fresh out of college who has dreamed his entire life of coming to Washington, D.C.. He truly believes that he can make a difference in this world of questionable morality. His best friend is Pete Komisky ( Mark-Paul Gosselaar), a lobbyist who sees the filth in D.C. for what it is, and doesn't think it will be cleaned up anytime soon. They are joined in their rowhouse by Mason's sister, Finley Scott ( Jacinda Barrett), who ditched graduate school for the adventure of Washington. Rounding out the happy home is Lewis Freeman ( Daniel Sunjata), a Supreme Court clerk, and his girlfriend Sarah Logan ( Kristanna Loken), a junior field producer for a cable news station.
