Answer the question at the end by quoting:

Grade was born in Tokmak, Taurida Governorate, Russian Empire to Isaak and Olga Winogradsky. In 1912, when Grade was six, the Jewish family emigrated to escape Cossack violence and anti-Semitism, from Odessa via Berlin to Brick Lane in Bethnal Green in the East End of London. Isaak worked as a trouser-presser while his three sons (Grade and his younger brothers, Bernard (later Bernard Delfont) and Leslie) attended the Rochelle Street Elementary School near Shoreditch, where Yiddish was spoken by 90% of the pupils. For two years the Winogradskys lived in rented rooms at the north end of Brick Lane, before moving to the nearby Boundary Estate.
In 1954, Grade was contacted by the manager of singer Jo Stafford, Mike Nidorf, who notified him of an advertisement in The Times inviting franchise bids for the new, commercial ITV network. Assembling a consortium that included impresarios Val Parnell and Prince Littler, the Incorporated Television Programme Company (ITP), which soon changed its name to Incorporated Television Company (ITC; also known as ITC Entertainment), was formed. ITC's bid to the Independent Television Authority (ITA) was rejected on the grounds of its conflict of interest from its prominence and involvement in artist management. The Associated Broadcasting Development Company (ABD) had gained ITA approval for both the London weekend and Midlands weekday contracts, but was undercapitalised; Grade's consortium joined with the ABD to form what became Associated Television (ATV). Reflecting his background in variety, Grade's favourite show and a success for the new company was Sunday Night at the London Palladium (1955-67, 1973-74), one of the most popular programmes on British television in its day. Grade did not avoid the other end of the cultural spectrum, and from 1958 Sir Kenneth Clark began to talk about the history of art on television. Meanwhile, Grade committed the funds for what would become the first trans-Atlantic success of the ITP subsidiary: The Adventures of Robin Hood (1955-60), commissioned by UK-based American producer Hannah Weinstein. ITC became a wholly owned ATV subsidiary in 1957, That same year ATV established a music publishing division with ATV Music and gained a half interest in Pye Records in 1959, later Pye became a wholly owned subsidiary.

Some context: Daniel Irvin Rather, Jr. was born on October 31, 1931, in Wharton County, Texas, the son of Daniel Irvin Rather, Sr., a ditch digger, and the former Byrl Veda Page. The Rathers moved to Houston, where Dan attended Love Elementary School and Hamilton Middle School. He graduated in 1950 from John H. Reagan High School in Houston. In 1953, he earned a bachelor's degree in journalism from Sam Houston State University where he was editor of the school newspaper, The Houstonian.
On September 8, 2004, Rather reported on 60 Minutes Wednesday that a series of memos critical of President George W. Bush's Texas Air National Guard service record had been discovered in the personal files of Lt. Bush's former commanding officer, Lt. Col. Jerry B. Killian. Once copies of the documents were made available on the Internet, their authenticity was quickly called into question. Much of this was based on the fact that the documents were proportionally printed and displayed using other modern typographic conventions usually unavailable on military typewriters of the 1970s. The font used on the documents has characteristics that exactly match standard font features of Microsoft Word. This led to claims that the memos were forgeries. The accusations then spread over the following days into mainstream media outlets including The Washington Post, The New York Times, and the Chicago Sun-Times. Rather and CBS initially defended the story, insisting that the documents had been authenticated by experts. CBS was contradicted by some of the experts it originally cited, and later reported that its source for the documents - former Texas Army National Guard officer Lt. Col. Bill Burkett - had misled the network about how he had obtained them. On September 20, CBS retracted the story. Rather stated, "If I knew then what I know now, I would not have gone ahead with the story as it was aired, and I certainly would not have used the documents in question." The controversy has been referred to by some as "Memogate" and "Rathergate." Following an investigation commissioned by CBS, CBS fired story producer Mary Mapes and asked three other producers connected with the story to resign. Many believe Rather's retirement was hastened by this incident. On September 20, 2007, Rather was interviewed on Larry King Live commenting "Nobody has proved that they were fraudulent, much less a forgery. ... The truth of this story stands up to this day."

IN: Elizabeth of York (11 February 1466 - 11 February 1503) was queen consort of England from 1486 until her death. As the wife of Henry VII, she was the first Tudor queen. She was the daughter of Edward IV and niece of Richard III, and she married the king following Henry's victory at the Battle of Bosworth which started the last phase of the Wars of the Roses. She was the mother of King Henry VIII.

Elizabeth's mother made an alliance with Lady Margaret Beaufort, mother of Henry Tudor, later King Henry VII, who had the closest claim to the throne of those in the Lancastrian party. Although Henry Tudor was descended from King Edward III, his claim to the throne was weak, due to an act of parliament passed during the reign of Richard II in the 1390s, that barred accession to the throne to any heirs of the legitimised offspring of Henry's great-great-grandparents, John of Gaunt and Katherine Swynford. Despite this, his mother and Elizabeth Woodville agreed Henry should move to claim the throne and, once he had taken it, marry Elizabeth of York to unite the two rival houses. In December 1483, in the cathedral in Rennes, Henry Tudor swore an oath promising to marry her and began planning an invasion. In 1484, Elizabeth of York and her sisters left Westminster Abbey and returned to court when Elizabeth Woodville was reconciled with Richard III, which may suggest that Elizabeth Woodville believed Richard III to be innocent of any possible role in the murder of her two sons (although this is unlikely owing to her involvement in Henry Tudor's failed invasion of October 1483). It was rumoured that Richard III intended to marry Elizabeth of York because his wife, Anne Neville, was dying and they had no surviving children. The Crowland Chronicle claimed that Richard III was forced to deny this unsavoury rumour. Soon after Anne Neville's death, Richard III sent Elizabeth away from court to the castle of Sheriff Hutton and opened negotiations with King John II of Portugal to marry his sister, Joan, Princess of Portugal, and to have Elizabeth marry their cousin, the future King Manuel I of Portugal. On 7 August 1485, Henry Tudor and his army landed in Wales and began marching inland. On 22 August 1485, Henry Tudor and Richard III fought the Battle of Bosworth Field. Richard III, despite having the larger army, was betrayed by one of his most powerful retainers, William Stanley, and died in battle. Henry Tudor took the crown by right of conquest as Henry VII.
