paragraph_text: Andy Bernard (Ed Helms) decides to throw a garden party at Schrute Farms to impress his parents and Robert California (James Spader), and exhaustively explains party manners to the office workers. Andy is jealous at the amount of attention his younger brother Walter Bernard, Jr. (Josh Groban) receives from his father, and thinks that by throwing an elaborate party he can ensure his father's blessings. At first, the party goes along smoothly. Andy makes a toast to Robert in order to get his fellow employees to toast him, as if to show to his parents and California that he is valued by his employees. His plan backfires, however, and instead more people toast Robert. To get everybody's mind off of Robert, Andy decides to sing ``More Than Words ''as a duet with his father. This too goes awry as his father corrects his playing and singing, and ultimately decides to sing a duet with Walter Jr. instead of Andy. Upset, Andy takes his guitar and storms off. His father confronts him privately about his outburst, and when Andy admits to trying to win his father's affection, he reacts with annoyance. This conversation is overheard by the other staff on the baby monitor Jim (John Krasinski) and Pam Halpert (Jenna Fischer) brought for their daughter, and Pam quickly turns off the monitor to let Andy save face. Darryl Philbin (Craig Robinson) and Oscar Martinez (Oscar Nunez) confide to the camera that they now understand why Andy feels he needs to prove himself to everyone. After his family leaves, a dejected Andy, feeling unwanted by his family and co-workers, says goodbye to the office staff as they turn the garden party into a barbecue. Darryl and Oscar, however, convince Andy to stay with a cheeseburger and a beer.

paragraph_text: While most artists became established in other formats before moving to adult contemporary, Michael Bublé and Josh Groban started out as AC artists. Throughout this decade, artists such as Nick Lachey, James Blunt, John Mayer, Bruno Mars, Jason Mraz, Kelly Clarkson, Adele, Clay Aiken and Susan Boyle have become successful thanks to a ballad heavy sound. Much as some hot AC and modern rock artists have crossed over into each other, so too has soft AC crossed with country music in this decade. Country musicians such as Faith Hill, Shania Twain, LeAnn Rimes and Carrie Underwood have had success on both charts.

paragraph_text: On April 7, 1979, the Easy Listening chart officially became known as Adult Contemporary, and those two words have remained consistent in the name of the chart ever since. Adult contemporary music became one of the most popular radio formats of the 1980s. The growth of AC was a natural result of the generation that first listened to the more "specialized" music of the mid-late 1970s growing older and not being interested in the heavy metal and rap/hip-hop music that a new generation helped to play a significant role in the Top 40 charts by the end of the decade.

paragraph_text: A notable pattern that developed during the 2000s and 2010s has been for certain pop songs to have lengthy runs on AC charts, even after the songs have fallen off the Hot 100. Adrian Moreira, senior vice president for adult music for RCA Music Group, said, "We've seen a fairly tidal shift in what AC will play". Rather than emphasizing older songs, adult contemporary was playing many of the same songs as top 40 and adult top 40, but only after the hits had become established. An article on MTV's website by Corey Moss describes this trend: "In other words, AC stations are where pop songs go to die a very long death. Or, to optimists, to get a second life."

paragraph_text: AC radio stations may play mainstream music, but they will exclude hip hop, dance tracks, hard rock, and some forms of teen pop, as they are less popular amongst the target demographic of these radio stations, which is intended for an adult audience. AC radio often targets the 25–44 age group, the demographic that has received the most attention from advertisers since the 1960s. A common practice in recent years is that many adult contemporary stations play less newer music because they also give ample airtime to hits of the past, so the de-emphasis on new songs slows the progression of the AC chart.
