Problem: Background: James was born in Holton, Kansas; his mother, died in 1954 when he was five. His father was a janitor and a handyman. After four years at the University of Kansas residing at Stephenson Scholarship hall, James joined the Army in 1971. He was the last person in Kansas to be sent to fight in the Vietnam War, although he never saw action there.
Context: An aspiring writer and obsessive fan, James began writing baseball articles after leaving the United States Army in his mid-twenties. Many of his first baseball writings came while he was doing night shifts as a security guard at the Stokely-Van Camp's pork and beans cannery. Unlike most writers, his pieces did not recount games in epic terms or offer insights gleaned from interviews with players. A typical James piece posed a question (e.g., "Which pitchers and catchers allow runners to steal the most bases?"), and then presented data and analysis written in a lively, insightful, and witty style that offered an answer.  Editors considered James's pieces so unusual that few believed them suitable for their readers. In an effort to reach a wider audience, James began self-publishing an annual book titled The Bill James Baseball Abstract beginning in 1977. The first edition, titled 1977 Baseball Abstract: Featuring 18 categories of statistical information that you just can't find anywhere else, presented 68 pages of in-depth statistics compiled from James's study of box scores from the preceding season and was offered for sale through a small advertisement in The Sporting News. Seventy-five people purchased the booklet. The 1978 edition, subtitled The 2nd annual edition of baseball's most informative and imaginative review, sold 250 copies. Beginning in 1979, James wrote an annual preview of the baseball season for Esquire, and continued to do so through 1984.  The first three editions of the Baseball Abstract garnered respect for James's work, including a very favorable review by Daniel Okrent in Sports Illustrated. New annual editions added essays on teams and players. By 1982 sales had increased tenfold, and a media conglomerate agreed to publish and distribute future editions.  While writers had published books about baseball statistics before (most notably Earnshaw Cook's Percentage Baseball, in the 1960s), few had ever reached a mass audience. Attempts to imitate James's work spawned a flood of books and articles that continues to this day.
Question: how many copies have been sold?
Answer: Seventy-five people purchased the booklet.

Problem: Background: James Stanley Brakhage ( BRAK-@j; January 14, 1933 - March 9, 2003), better known as Stan Brakhage, was an American non-narrative filmmaker. He is considered to be one of the most important figures in 20th-century experimental film. Over the course of five decades, Brakhage created a large and diverse body of work, exploring a variety of formats, approaches and techniques that included handheld camerawork, painting directly onto celluloid, fast cutting, in-camera editing, scratching on film, collage film and the use of multiple exposures. Interested in mythology and inspired by music, poetry, and visual phenomena, Brakhage sought to reveal the universal in the particular, exploring themes of birth, mortality, sexuality, and innocence.
Context: When Brakhage's early films had been exhibited in the 1950s, they had often been met with derision, but in the early 1960s Brakhage began to receive recognition in exhibitions and film publications, including Film Culture, which gave awards to several of his films, including The Dead, in 1962. The award statement, written by Jonas Mekas, a critic who would later become an influential experimental filmmaker in his own right, cited Brakhage for bringing to cinema "an intelligence and subtlety that is usually the province of the older arts." Writer/critic Guy Davenport, an ardent admirer of Brakhage, invited him to the University of Kentucky in March 1964 and tried to get him a residency there.  From 1961 to 1964, Brakhage worked on a series of 5 films known as the Dog Star Man cycle. The Brakhages moved to Lump Gulch, Colorado in 1964, though Brakhage continued to make regular visits to New York. During one of those visits, the 16mm film equipment he had been using was stolen. Brakhage couldn't afford to replace it, instead opting to buy cheaper 8mm film equipment. He soon began working in the format, producing a 30-part cycle of 8mm films known as the Songs from 1964 to 1969. The Songs include one of Brakhage's most acclaimed films, 23rd Psalm Branch, a response to the Vietnam War and its presentation in the mass media.  Brakhage began teaching film history and aesthetics at the School of the Art Institute of Chicago in 1969, commuting from his home in Colorado.
Question: What else did he receive attention for n the early 60s?
Answer: From 1961 to 1964, Brakhage worked on a series of 5 films known as the Dog Star Man cycle.

Problem: Background: Lee de Forest was born in 1873 in Council Bluffs, Iowa, the son of Anna Margaret (nee Robbins) and Henry Swift DeForest. He was a direct descendant of Jesse de Forest, the leader of a group of Walloon Huguenots who fled Europe in the 17th Century due to religious persecution. De Forest's father was a Congregational Church minister who hoped his son would also become a pastor. In 1879 the elder de Forest became president of the American Missionary Association's Talladega College in Talladega, Alabama, a school "open to all of either sex, without regard to sect, race, or color", and which educated primarily African-Americans.
Context: At the 1904 Louisiana Purchase Exposition, Valdemar Poulsen had presented a paper on an arc transmitter, which unlike the discontinuous pulses produced by spark transmitters, created steady "continuous wave" signals that could be used for amplitude modulated (AM) audio transmissions. Although Poulsen had patented his invention, de Forest claimed to have come up with a variation that allowed him to avoid infringing on Poulsen's work. Using his "sparkless" arc transmitter, de Forest first transmitted audio across a lab room on December 31, 1906, and by February was making experimental transmissions, including music produced by Thaddeus Cahill's telharmonium, that were heard throughout the city.  On July 18, 1907, de Forest made the first ship-to-shore transmissions by radiotelephone -- race reports for the Annual Inter-Lakes Yachting Association (I-LYA) Regatta held on Lake Erie -- which were sent from the steam yacht Thelma to his assistant, Frank E. Butler, located in the Fox's Dock Pavilion on South Bass Island. De Forest also interested the U.S. Navy in his radiotelephone, which placed a rush order to have 26 arc sets installed for its Great White Fleet around-the-world voyage that began in late 1907. However, at the conclusion of the circumnavigation the sets were declared to be too unreliable to meet the Navy's needs and removed.  The company set up a network of radiotelephone stations along the Atlantic coast and the Great Lakes, for coastal ship navigation. However, the installations proved unprofitable, and by 1911 the parent company and its subsidiaries were on the brink of bankruptcy.
