Some context: John William Carson (October 23, 1925 - January 23, 2005) was an American television host, comedian, writer, and producer. He is best known as the host of The Tonight Show Starring Johnny Carson (1962-1992). Carson received six Emmy Awards, the Television Academy's 1980 Governor's Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987.
Carson began his broadcasting career in 1950 at WOW radio and television in Omaha, Nebraska. Carson soon hosted a morning television program called The Squirrel's Nest. One of his routines involved interviewing pigeons on the roof of the local courthouse that would report on the political corruption they had seen. Carson supplemented his income by serving as master of ceremonies at local church dinners, attended by some of the same politicians and civic leaders whom he had lampooned on the radio. The wife of one of the Omaha political figures Carson spoofed owned stock in a radio station in Los Angeles, and in 1951 referred Carson to her brother, who was influential in the emerging television market in southern California. Carson joined CBS-owned Los Angeles television station KNXT. In 1953, comic Red Skelton--a fan of Carson's "cult success" low-budget sketch comedy show, Carson's Cellar (1951 to 1953) on KNXT--asked Carson to join his show as a writer. In 1954, Skelton during rehearsal accidentally knocked himself unconscious an hour before his live show began, and Carson successfully filled in for him. In 1955, Jack Benny invited Carson to appear on one of his programs during the opening and closing segments. Carson imitated Benny and claimed that Benny had copied his gestures. Benny predicted that Carson would have a successful career as a comedian. Carson hosted several shows besides Carson's Cellar, including the game show Earn Your Vacation (1954) and the CBS variety show The Johnny Carson Show (1955-1956). He was a guest panelist on the original To Tell the Truth starting in 1960, later becoming a regular panelist from 1961 until 1962. After the prime time The Johnny Carson Show failed, he moved to New York City to host Who Do You Trust? (1957-1962), formerly known as Do You Trust Your Wife?. In 1958, he appeared as a guest star in an episode entitled "Do You Trust Your Wife" on NBC's short-lived variety show, The Polly Bergen Show. On Who Do You Trust?, Carson met his future sidekick and straight man, Ed McMahon. Although he believed moving to daytime would hurt his career, Who Do You Trust? was a success. It was the first show where he could ad lib and interview guests, and because of Carson's on-camera wit, the show became "the hottest item on daytime television" during his five years at ABC.

Question: The Jay Leno Show is an American talk show created by and starring Jay Leno. Premiering on NBC on September 14, 2009, the program aired on weeknights at 10:00 p.m. ET/PT through February 9, 2010. The program was modeled upon the format of a late night talk show--specifically, Jay Leno's incarnation of The Tonight Show, opening with a comedic monologue, followed by interviews with celebrity guests and other comedy segments. Sketches from The Tonight Show (including Headlines and Jaywalking) were carried over to The Jay Leno Show, along with new sketches.

Leno had a contract for five years for the show. NBC reportedly had an option to cancel after two years, but had committed to at least one or two years regardless of ratings, although later chose to end the show after less than five months. He could have earned up to $30 million each year depending on ratings for Leno, compared to a $20 million annual salary during his last years at Tonight. NBC expected to benefit by offering an inexpensive comedic alternative to the procedurals ("100% more comedy and 98% fewer murders!") and other one-hour dramas that typically air at 10 pm, and by offering new episodes 46 weeks each year versus 22. While Leno was not necessarily expected to be competitive with the higher-rated scripted shows on ABC and CBS in its time slot, its projected cost of production was far lower and thus it was expected to be profitable to the network, and product integration intended to make the show "as DVR-proof as you can be on television in this era". Each airing of Leno cost about $350,000 to $400,000 versus up to $3 million for an hour-long drama, saving NBC $13 million each week without the network needing the show to beat its competitors. Those costs include the services of 22 writers, whom Leno called the "top 5% of the highest-paid . . . in the Guild." McDonald's became the first buying advertiser for the program, tying in their "Million Dollar Roll" nightly in October 2009 promoting that year's version of McDonald's Monopoly.

Using a quote from the above article, answer the following question: How did NBC benefit from this?
HHHHHH
Answer: saving NBC $13 million each week without the network needing the show to beat its competitors.

Some context: Brandreth was born in Wuppertal, Germany, where his father, Charles Brandreth, was serving as a legal officer with the Allied Control Commission. After having moved to London with his parents at the age of three, Brandreth was educated at the Lycee Francais Charles de Gaulle (as it is called today), Bedales School, where he met his friend Simon Cadell, and New College, Oxford. He was President of the Oxford Union in Michaelmas Term, 1969 and edited the university magazine Isis. He was described in a contemporaneous publication as "Oxford's Lord High Everything Else".
He is a former European Monopoly champion, and President of the Association of British Scrabble Players, having organised the first British National Scrabble Championship in 1971. He is also the President of The Oscar Wilde Society. The society was founded in September 1990, by a group of fans of Wilde and his work, it is a non-profit organisation that aims to increase knowledge, enjoyment and study of Wilde's life, personality and works. It organises lectures, readings and discussions, as well as visits to places connected with him. Brandreth hosts an annual Oscar Wilde party to celebrate the writer's birth. These parties are often attended by such people as Stephen Fry, Joanna Lumley, Derek Jacobi, Camilla, Duchess of Cornwall and Julian Fellowes. The venues are often places of interest in Wilde's life, for example the Langham where A Picture of Dorian Gray was commissioned. In August 2005, he appeared in a production of Shakespeare's Twelfth Night at the Edinburgh Festival. He is an after-dinner speaker, and he held the world record for the longest continuous after-dinner speech, at 12 and a half hours, done as a charity stunt. With his wife he founded the Teddy Bear museum; formerly located in Stratford-upon-Avon for 18 years, it was relocated to the Polka Theatre in Wimbledon, London and as of 2016 it is on display at Newby Hall in Yorkshire. He is a patron of the National Piers Society and vice-president of charity Fields in Trust (formerly the National Playing Fields Association). He was appointed as Chancellor of the University of Chester in December 2016.
