Mayberry R.F.D. is an American television series produced as a spin-off and direct continuation of The Andy Griffith Show. When star Andy Griffith decided to leave his series, most of the supporting characters returned for the new program, which ran for three seasons (78 episodes) on the CBS Television Network from 1968–1971. During the final season of The Andy Griffith Show, widower farmer Sam Jones (Ken Berry) and his young son Mike (Buddy Foster) are introduced and gradually become the show's focus. Sheriff Andy Taylor takes a backseat in the storylines, establishing the sequel series. The show's first episode, "Andy and Helen's Wedding", had the highest ratings in recorded television history (up to premiere date in 1968). Sheriff Taylor and newlywed wife Helen make guest appearances on RFD until late 1969, and then relocate with Opie. Mayberry R.F.D. was popular throughout its entire run, but was canceled after its third season in CBS's infamous "rural purge" of 1971. R.F.D. stands for "Rural Free Delivery", a quaint postal depiction of the rural Mayberry community.
In general, a rural area is a geographic area that is located outside cities and towns. The Health Resources and Services Administration of the U.S. Department of Health and Human Services defines the word "rural" as encompassing "...all population, housing, and territory not included within an urban area. Whatever is not urban is considered rural."
Typical rural areas have a low population density and small settlements. Agricultural areas are commonly rural, though so are others such as forests. Different countries have varying definitions of "rural" for statistical and administrative purposes.
The United States Postal Service (USPS), also known as the Post Office and U.S. Mail, is an independent agency of the United States federal government responsible for providing postal service in the United States. It is one of the few government agencies explicitly authorized by the United States Constitution. The USPS traces its roots to 1775 during the Second Continental Congress, where Benjamin Franklin was appointed the first postmaster general. The cabinet-level Post Office Department was created in 1792 from Franklin's operation and transformed into its current form in 1971 under the Postal Reorganization Act.
The USPS employed 522,144 workers and operated 212,530 vehicles in 2012. The USPS is the operator of the largest civilian vehicle fleet in the world. The USPS is legally obligated to serve all Americans, regardless of geography, at uniform price and quality. The USPS has exclusive access to letter boxes marked "U.S. Mail" and personal letterboxes in the United States, but still competes against private package delivery services, such as UPS and FedEx.
Rural delivery service refers to services for the delivery of mail to rural areas. Examples include Rural Free Delivery in the United States and the Rural Mail Box addressing system in Australia. Such services may be based on post roads, or may make use of alternate forms of transport, such as mail delivery by animal, including dogs and pigeons.
Such services are in contrast to those suitable only to urban areas, such as the Prague pneumatic post and the London Pneumatic Despatch Company.
