full_context: Document 1: IPod: Universal Music Group decided not to renew their contract with the iTunes Store on July 3, 2007. Universal will now supply iTunes in an 'at will' capacity.

Document 3: The Tonight Show Starring Johnny Carson: Carson hosted his penultimate show, featuring guests Robin Williams and Bette Midler, on May 21, 1992. The last of Carson's monologues was delivered on this episode and was written by Jim Mulholland, Steven Kunes and Rift Fournier. Once underway, the atmosphere was electric and Carson was greeted with a sustained, two - minute intense standing ovation. Williams was especially uninhibited with his trademark manic energy and stream - of - consciousness lunacy. Midler was more emotional. When the conversation turned to Johnny's favorite songs, ``I'll Be Seeing You ''and`` Here's That Rainy Day'', Midler mentioned that she knew a chorus of the latter. She began singing the song, and after the first line, Carson joined in and turned it into an impromptu duet. Midler finished her appearance from center stage, where she slowly sang the pop standard ``One for My Baby (and One More for the Road) ''. Carson became unexpectedly tearful, and a shot of the two of them was captured by a camera angle from across the set that has never been broadcast. The audience became tearful as well and called the three performers out for a second bow after the taping was completed. This show was immediately recognized as a television classic that Midler considered one of the most emotional moments of her life and eventually won an Emmy for her role in it.

Document 7: Sony Music: Sony Music Entertainment Inc. (sometimes known as Sony Music or by the initials, SME) is an American music corporation managed and operated by Sony Corporation of America (SCA), a subsidiary of Japanese conglomerate Sony Corporation.

It is the world's second largest recorded music company, after Universal Music Group.

Document 12: Phonograph record: In 1968, Reprise planned to release a series of 78 rpm singles from their artists on their label at the time, called the Reprise Speed Series. Only one disc actually saw release, Randy Newman's I Think It's Going to Rain Today, a track from his self-titled debut album (with The Beehive State on the flipside). Reprise did not proceed further with the series due to a lack of sales for the single, and a lack of general interest in the concept. Guitarist & vocalist Leon Redbone released a promotional 78 rpm record in 1978 featuring two songs (Alabama Jubilee and Please Don't Talk About Me When I'm Gone) from his Champagne Charlie album. In 1980 Stiff Records in the United Kingdom issued a 78 by Joe "King" Carrasco containing the songs Buena (Spanish for "good," with the alternate spelling "Bueno" on the label) and Tuff Enuff. Underground comic cartoonist and 78 rpm record collector Robert Crumb released three discs with his Cheap Suit Serenaders in the 1980s.
Document 13: Seasons (Bing Crosby album): Seasons is a 1977 vinyl album by Bing Crosby which was issued by Polydor Records under catalogue No. 2442 151. The album is particularly significant in that it was the final studio album completed before Crosby's death on October 14, 1977; it was released posthumously, and was marketed with the tagline "The Closing Chapter". Crosby was backed by Pete Moore and his Orchestra and the Johnny Evans Singers. Moore also did all the arrangements for the album, which was recorded at CBS Studios, Whitfield Street, London on September 12,13 & 14 1977 - except for one song "Spring Will Be a Little Late This Year" which was recorded at United Western Recorders, Sunset Boulevard, Hollywood on January 19, 1976. This song was also produced by Ken Barnes and arranged by Pete Moore.
Document 14: Phonograph record: The older 78 format continued to be mass-produced alongside the newer formats using new materials until about 1960 in the U.S., and in a few countries, such as India (where some Beatles recordings were issued on 78), into the 1960s. For example, Columbia Records' last reissue of Frank Sinatra songs on 78 rpm records was an album called Young at Heart, issued November 1, 1954. As late as the 1970s, some children's records were released at the 78 rpm speed. In the United Kingdom, the 78 rpm single lasted longer than in the United States and the 45 rpm took longer to become popular. The 78 rpm was overtaken in popularity by the 45 rpm in the late 1950s, as teenagers became increasingly affluent.
Document 15: 8-track tape: There is a debate among collectors about the last commercial eight - track released by a major label, but the fan / enthusiast internet website ``8 Track Heaven ''can not find a major label release past Fleetwood Mac's Greatest Hits in November 1988. Radio Shack (Tandy Corporation) continued to sell blank eight - track cartridges for home recording use under its Realistic brand until 1990.
