Context paragraphs:
Academic drama: Academic drama is a theatrical movement that emerged in the mid 16th century during the Renaissance.  Dedicated to the study of classical dramas for the purpose of higher education, universities in England began to produce the plays of Sophocles, Euripides, and Seneca the Younger (among others) in the Greek and Roman languages, as well as neoclassical dramas.  These classical and neoclassical productions were performed by young scholars at universities in Cambridge and Oxford.  Other European countries, such as Spain and Italy adapted classical plays into a mixture of Latin and vernacular dramas.  These Spanish and Italian adaptations were used in teaching morals in schools and colleges.  The intellectual development of dramas in schools, universities, and Inns of Court in Europe allowed the emergence of the great playwrights of the late 16th century.

The After-Dinner Joke: The After-Dinner Joke is a television play in the epic form written by the English playwright Caryl Churchill for the BBC1 "Play for Today" series which was broadcast on 14 February 1978.

LGBT student movement: The origin of the LGBT student movement can be linked to other activist movements from the mid-20th century in the United States.  The Civil Rights Movement and Second-wave feminist movement were working towards equal rights for other minority groups in the United States.  Though the student movement began a few years before the Stonewall riots, the riots helped to spur the student movement to take more action in the US.  Despite this, the overall view of these gay liberation student organizations received minimal attention from contemporary LGBT historians.  This oversight stems from the idea that the organizations were founded with haste as a result of the riots.  Others historians argue that this group gives too much credit to groups that disagree with some of the basic principles of activist LGBT organizations.

Restoration Movement: The Restoration Movement (also known as the American Restoration Movement or the Stone-Campbell Movement, and pejoratively as Campbellism) is a Christian movement that began on the United States frontier during the Second Great Awakening (1790–1840) of the early 19th century.  The pioneers of this movement were seeking to reform the church from within and sought "the unification of all Christians in a single body patterned after the church of the New Testament."  Especially since the mid-20th century, members of these churches do not identify as Protestant but simply as Christian.

Eye movement in reading: Eye movement in reading involves the visual processing of written text.  This was described by the French ophthalmologist Louis Émile Javal in the late 19th century.  He reported that eyes do not move continuously along a line of text, but make short, rapid movements (saccades) intermingled with short stops (fixations).  Javal's observations were characterised by a reliance on naked-eye observation of eye movement in the absence of technology.  From the late 19th to the mid-20th century, investigators used early tracking technologies to assist their observation, in a research climate that emphasised the measurement of human behaviour and skill for educational ends.  Most basic knowledge about eye movement was obtained during this period.  Since the mid-20th century, there have been three major changes: the development of non-invasive eye-movement tracking equipment; the introduction of computer technology to enhance the power of this equipment to pick up, record and process the huge volume of data that eye movement generates; and the emergence of cognitive psychology as a theoretical and methodological framework within which reading processes are examined.  Sereno & Rayner (2003) believed that the best current approach to discover immediate signs of word recognition is through the recordings of eye movements and event-related potential.

Skyhook (cable): A skyhook is a "hook" used to lift an object on a long cable hanging from the sky, without readily apparent support.  In the mid-20th century it was common in the Boy Scouts and occupations such as oil drilling to send new recruits on a futile search for such an imaginary object, as a practical joke.  The term has subsequently lent its name to some real mechanisms that use an airborne hook or hoist, and to other products or ideas that allude to the concept.  The American philosopher Richard Rorty uses the term to refer to a hypothetical metaphysical system that leads to a universal perspective.

Spanish Colonial Revival architecture: The Spanish Colonial Revival Style is a United States architectural stylistic movement arising in the early 20th century based on the Spanish Colonial architecture of the Spanish colonization of the Americas.

Crossroads dance: The crossroads dance was a type of social event popular in Ireland up to the mid-20th century, in which people would congregate at the large cleared space of a crossroads to dance.  In contrast to the later ceili styles, crossroad dances were generally set dancing or solo dancing.  The crossroads dance declined in popularity in the mid-20th century, due to rural depopulation, musical recordings, and pressure of the Catholic clergy which resulted in the Public Dance Halls Act of 1935 which restricted all dancing to licensed establishments.  In the early 1930s the wooden platforms at crossroads became the focus of standoffs and faction fights between Fianna Fáil and the Blueshirts, with some destroyed by arson.  The phrase "comely maidens dancing at the crossroads", a misquotation attributed to Éamon De Valera's 1943 Patrick's Day radio broadcast, has become shorthand for a maudlin yearning for a vanished Irish rural idyll.

Epic theatre: Epic theatre (German: "episches Theater" ) is a theatrical movement arising in the early to mid-20th century from the theories and practice of a number of theatre practitioners who responded to the political climate of the time through the creation of a new political theatre.  These practitioners included Erwin Piscator, Vladimir Mayakovsky, Vsevolod Meyerhold and, most famously, Bertolt Brecht.

British folk revival: The British folk revival incorporates a number of movements for the collection, preservation and performance of traditional music in the United Kingdom and related territories and countries, which had origins as early as the 18th century.  It is particularly associated with two movements, usually referred to as the first and second revivals, respectively in the late 19th to early 20th centuries and the mid-20th century.  The first included increased interest in and study of traditional music, the second was a part of the birth of contemporary folk music.  These had a profound impact on the development of British classical music and in the creation of a "national" or "pastoral school" and led to the creation of a sub-culture of folk clubs and folk festivals as well as influential subgenres including progressive folk music and electric folk.
