In the United States and Canada, most government offices are closed on both Saturday and Sunday. The practice of offices closing on Sunday in government and in some rural areas of the United States stem from a system of blue laws. Blue laws were established in the early puritan days which forbade secular activities on Sunday and were rigidly enforced. Some public activities are still regulated by these blue laws in the 21st century. In 1985 twenty-two states in which religious fundamentalism remained strong maintained general restrictions on Sunday behavior. In Oklahoma, for example, it is stated: "Oklahoma's statutes state that "acts deemed useless and serious interruptions of the repose and religious liberty of the community," such as trades, manufacturing, mechanical employment, horse racing, and gaming are forbidden. Public selling of commodities other than necessary foods and drinks, medicine, ice, and surgical and burial equipment, and other necessities can legally be prohibited on Sunday. In Oklahoma a fine not to exceed twenty-five dollars may be imposed on individuals for each offense." Because of these blue laws, many private sector retail businesses open later and close earlier on Sunday or don't open at all. Many countries, particularly in Europe such as Sweden, France, Germany and Belgium, but also in other countries such as Peru, hold their national and local elections on a Sunday, either by law or by tradition. Many American and British daily newspapers publish a larger edition on Sundays, which often includes color comic strips, a magazine, and a coupon section; may only publish on a Sunday, or may have a "sister-paper" with a different masthead that only publishes on a Sunday. North American radio stations often play specialty radio shows such as Casey Kasem's countdown or other nationally syndicated radio shows that may differ from their regular weekly music patterns on Sunday morning or Sunday evening. In the United Kingdom, there is a Sunday tradition of chart shows on BBC Radio 1 and commercial radio; this originates in the broadcast of chart shows and other populist material on Sundays by Radio Luxembourg when the Reithian BBC's Sunday output consisted largely of solemn and religious programmes. The first Sunday chart show was broadcast on the Light Programme on 7 January 1962, which was considered a radical step at the time. BBC Radio 1's chart show moved to Fridays in July 2015 but a chart update on Sundays was launched in July 2019. Period or older-skewing television dramas, such as "Downton Abbey", "Call the Midwife", "Lark Rise to Candleford" and "Heartbeat" are commonly shown on Sunday evenings in the UK; the first of these was "Dr Finlay's Casebook" in the 1960s.
