Question: Who owns the streaming platform that Serial was ranked number one before its debut? Passage 1:Cissé was born in Niamey, Niger. As a child he assumed that he would work in his father's law firm. He became interested in science through Hollywood films. In Niamey there were few opportunities to practise science as his school did not have a laboratory. He was keen to move to America to study, and completed high school two years early. He moved to the United States at the age of 17 to attend college. Cissé studied physics at the North Carolina Central University and graduated in 2004. During his undergraduate degree he was encouraged by Carl Wieman to apply for a fellowship, and spent a summer at Princeton University working in condensed matter physics. During this summer project he looked at jammed disordered packings, investigating how M&M's arrange in a small volume with Paul Chaikin. Cissé used various techniques to study jammed packings, including magnetic resonance imaging, but in the end used a much simpler approach - painting M&M's and analysing how many times they knocked into each other. The result was published in Science. He moved to Urbana for his graduate studies, and earned his PhD under the supervision of single molecule biophysicist Taekjip Ha at the University of Illinois at Urbana–Champaign in 2009. After completing his doctorate, Cissé joined the École Normale Supérieure in Paris. He worked as a Pierre Gilles de Gennes Fellow in the joint labs of a physicist, Maxime Dahan, and a biologist, Xavier Darzacq. He also held a long-term fellowship with the European Molecular Biology Organization. In Paris, Cissé developed the single-cell microscopy technique time-correlated photoactivated localization microscopy (tcPALM), allowing for time resolved measurements in vitro. Cissé used transient-PALM to demonstrated that RNA polymerase II forms clusters that deconstruct after their work is done. Until Cissé made this discovery it was assumed that RNA polymerases were stable.
 Passage 2:Serial is an investigative journalism podcast hosted by Sarah Koenig, narrating a nonfiction story over multiple episodes. The series was co-created and is co-produced by Koenig and Julie Snyder and developed by This American Life. Season one investigated the 1999 murder of Hae Min Lee (Hangul: 이해민), an 18-year-old student at Woodlawn High School in Baltimore. Season two focused on Sergeant Bowe Bergdahl, an American Army soldier who was held for five years by the Taliban, and then charged with desertion. Season three, which debuted in September 2018, explores cases within the Justice Center Complex in the Cleveland area. Serial ranked number one on iTunes even before its debut and remained there for several weeks. Serial won a Peabody Award in April 2015 for its innovative telling of a long-form nonfiction story. As of September 2018, episodes of seasons one and two have been downloaded over 340 million times, establishing an ongoing podcast world record.
 Passage 3:The Guitar Hero series (sometimes referred to as the Hero series) is a series of music rhythm games first published in 2005 by RedOctane and Harmonix, and distributed by Activision, in which players use a guitar-shaped game controller to simulate playing lead, bass guitar, and rhythm guitar across numerous rock music songs. Players match notes that scroll on-screen to colored fret buttons on the controller, strumming the controller in time to the music in order to score points, and keep the virtual audience excited. The games attempt to mimic many features of playing a real guitar, including the use of fast-fingering hammer-ons and pull-offs and the use of the whammy bar to alter the pitch of notes. Most games support single player modes, typically a Career mode to play through all the songs in the game, and both competitive and cooperative multiplayer modes. With the introduction of Guitar Hero World Tour in 2008, the game includes support for a four-player band including vocals and drums. The series initially used mostly cover versions of songs created by WaveGroup Sound, but most recent titles feature soundtracks that are fully master recordings, and in some cases, special re-recordings, of the songs. Later titles in the series feature support for downloadable content in the form of new songs.
