Answer the question at the end by quoting:

Chayefsky was born in The Bronx, New York City to Russian Jewish immigrants Harry and Gussie Stuchevsky Chayefsky who came from Moscow to New York in 1907. He had two older brothers, William and Isidor. He spent part of his youth in Mount Vernon, New York.
He moved into television with scripts for Danger, The Gulf Playhouse and Manhunt. Philco Television Playhouse producer Fred Coe saw the Danger and Manhunt episodes and enlisted Chayefsky to adapt the story It Happened on the Brooklyn Subway about a photographer on a New York subway train who reunites a concentration camp survivor with his long-lost wife. Chayefsky's first script to be telecast was a 1949 adaptation of Budd Schulberg's What Makes Sammy Run? for Philco. Since he had always wanted to use a synagogue as backdrop, he wrote Holiday Song, telecast in 1952 and also in 1954. He submitted more work to Philco, including Printer's Measure, The Bachelor Party (1953) and The Big Deal (1953). One of these teleplays, Mother (April 4, 1954), received a new production October 24, 1994 on Great Performances with Anne Bancroft in the title role. Curiously, original teleplays from the 1950s are almost never revived for new TV productions, so the 1994 production of Mother was a conspicuous rarity. In 1953, Chayefsky wrote Marty, which was premiered on The Philco Television Playhouse, with Rod Steiger and Nancy Marchand. Marty is about a decent, hard-working Bronx butcher, pining for the company of a woman in his life but despairing of ever finding true love in a relationship. Fate pairs him with a plain, shy schoolteacher named Clara whom he rescues from the embarrassment of being abandoned by her blind date in a local dance hall. The production, the actors and Chayefsky's naturalistic dialogue received much critical acclaim and influenced subsequent live television dramas. Chayefsky had a unique clause in his Marty contract that stated that only he could write the screenplay, which he did for the 1955 movie. Chayefsky's The Great American Hoax was broadcast May 15, 1957 during the second season of The 20th Century Fox Hour. This was actually a rewrite of his earlier Fox film, As Young as You Feel (1951) with Monty Woolley and Marilyn Monroe. The Great American Hoax was shown on the FX channel after Fox restored some The 20th Century Fox Hour episodes and telecast them under the new title Fox Hour of Stars beginning in 2002.

Did he do any other ones?

Since he had always wanted to use a synagogue as backdrop, he wrote Holiday Song, telecast in 1952 and also in 1954. He submitted more work to Philco,

IN: 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 did not expect his show to beat competing first-run episodes, but to do better than reruns, in part because topical jokes benefit from the "immediacy" of the time slot versus 11:30 pm. A television analyst predicted that Leno would finish in "a safe third place" every night. NBC research before the show's debut indicated that fans of Leno would watch Leno two to three times a week. NBC saw a 1.5 rating for the show in the 18-49 demographic as "viable" and a 1.8 as a "home run". NBC told Leno that at a 1.5 rating, NBC makes $300 million a year. Tonight at 11:30 pm earned about a 1.3 to 1.5; the television audience at 10 pm is 40% larger than at 11:30 pm, and the network hoped Leno's audience would also grow. Industry observers have cited a range of ratings, from 1.7 to 2, as being necessary for the show to succeed at 10 pm. By comparison, 2.5 is generally necessary for a 10 pm drama to succeed; those that earned a 1.7 or less during the 2008-2009 season were generally cancelled. NBC's prime-time dramas averaged about 2 during 2008-2009. The first episode of The Jay Leno Show earned "fast national" estimates of 17.7 million viewers, an 11 Nielsen rating (5.1 among persons 18-49) and an 18 share, significantly above both his Tonight finale and the debut of The Tonight Show with Conan O'Brien in all categories. By the second week and competing against season premieres, the audience fell to six million viewers, still on par with or exceeding NBC projections. As of November 1, 2009, The Jay Leno Show has averaged a 1.98 in the adults 18-49 ratings and 6.594 million viewers. During the week before Christmas, the ratings dropped to 1.4 during the week. Prior to the controversy regarding the move of the Jay Leno Show to 11:35 p.m., viewership bottomed out at 4.799 million viewers, although there was a slight bump as word of the controversy broke. Though the show had been meeting the network's projections for the show itself, it has been severely detrimental to the ratings of the late local news on NBC affiliates. Several stations across the country have seen what is known as the "Leno Effect", where the lower audience for Leno (as compared to NBC's scripted prime time offerings) translated directly into a domino effect of severe audience drops for late local news (on the order of 25-30%), effects that NBC had underestimated.
