In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Blender described Jackson as the "late 20th century's preeminent pop icon", while The New York Times gave the opinion that he was a "musical phenomenon" and that "in the world of pop music, there is Michael Jackson and there is everybody else". Jackson changed the way the industry functioned: both as an artistic persona and as a financial, profitable entity. His attorney John Branca observed that Jackson achieved the highest royalty rate in the music industry to that point: approximately $2 (US$4.82 in 2018 dollars) for each album sold.
As a result, Jackson earned record-breaking profits from compact disc sales and from the sale of copies of the documentary, The Making of Michael Jackson's Thriller, produced by Jackson and John Landis. Funded by MTV, the film sold over 350,000 copies in its first few months. In a market then driven by singles, Thriller raised the significance of albums, yet its multiple hit singles changed perceived notions as to the number of successful singles that could be taken from an individual album. The era saw the arrival of novelties like the Michael Jackson doll, that appeared in stores in May 1984 at a price of $12 (US$29 in 2018 dollars). Thriller retains a position in American culture; biographer J. Randy Taraborrelli explains, "At some point, Thriller stopped selling like a leisure item—like a magazine, a toy, tickets to a hit movie—and started selling like a household staple".At the time of the album's release, a press statement from Gil Friesen, the then President of A&M Records, read that, "The whole industry has a stake in this success". Time magazine speculated that "the fallout from Thriller has given the [music] business its best years since the heady days of 1978, when it had an estimated total domestic revenue of $4.1 billion". Time summed up Thriller's impact as a "restoration of confidence" for an industry bordering on "the ruins of punk and the chic regions of synthesizer pop". The publication described Jackson's influence at that point as, "Star of records, radio, rock video. A one-man rescue team for the music business. A songwriter who sets the beat for a decade. A dancer with the fanciest feet on the street. A singer who cuts across all boundaries of taste and style and color too".
