A county town is a county's administrative centre in the United Kingdom or Ireland. County towns are usually the location of administrative or judicial functions, or established over time as the de facto main town of a county. The concept of a county town eventually became detached from its original meaning of where the county administration is based (see County halls below). In fact, many county towns are no longer part of "their" administrative county. For example, Nottingham is administered by a unitary authority entirely separate from the rest of Nottinghamshire. Many county towns are in fact cities, but all are referred to as county towns irrespective of whether city status is held or not.

Note - Despite the fact that Belfast is the capital of Northern Ireland, it is not the county town of any county. Greater Belfast straddles two counties (Antrim and Down).

Oprah Winfrey (born Orpah Gail Winfrey; January 29, 1954) is an American media proprietor, talk show host, actress, producer, and philanthropist. Winfrey is best known for her self-titled, multi-award-winning talk show, which has become the highest-rated program of its kind in history and was nationally syndicated from 1986 to 2011. She has been ranked the richest African-American of the 20th century, the greatest black philanthropist in American history, and was for a time the world's only black billionaire. She is also, according to some assessments, the most influential woman in the world.

Winfrey was born into poverty in rural Mississippi to a teenage single mother and later raised in an inner-city Milwaukee neighborhood. She experienced considerable hardship during her childhood, claiming to be raped at age nine and becoming pregnant at 14; her son died in infancy. Sent to live with the man she calls her father, a barber in Tennessee, Winfrey landed a job in radio while still in high school and began co-anchoring the local evening news at the age of 19. Her emotional ad-lib delivery eventually got her transferred to the daytime-talk-show arena, and after boosting a third-rated local Chicago talk show to first place, she launched her own production company and became internationally syndicated.
