Question: Steven Randall "Randy" Jackson's sister has been a prominent figure in popular culture for over how many years?

<P0-S0> Andi Zeisler (born c. 1972) is a co-founder and creative/editorial director of "Bitch Media", a nonprofit feminist media organization based in Portland, Oregon. <P0-S1>  Zeisler's writing, which focuses mainly on feminist interpretations of popular culture, has been featured in a variety of publications including "Mother Jones", the "San Francisco Chronicle", Utne Reader, The Women's Review of Books, and "Ms." She is a former pop-music columnist for the "SF Weekly" and the "East Bay Express", and also contributed to the anthologies "Young Wives' Tales", "Secrets and Confidences: The Complicated Truth About Women's Friendships" (both from Seal Press), and "Howl: A Collection of the Best Contemporary Dog Wit" (Crown). <P0-S2>  She is the coeditor of "BitchFest: 10 Years of Cultural Criticism from the Pages of Bitch Magazine", and a book about feminism and popular culture for Seal Press, "Feminism and Pop Culture". <P0-S3>  She frequently speaks on issues of feminism and popular culture on college and university campuses. <SEP> <P1-S0> Janet Damita Jo Jackson (born May 16, 1966) is an American singer, songwriter, dancer and actress. <P1-S1>  Known for sonically innovative, socially conscious, and sexually provocative records, elaborate stage shows, and high-profile television and film roles, she has been a prominent figure in popular culture for over 30 years. <SEP> <P2-S0> The Crow Terrace Poetry Trial (or Crow Terrace Poetry Case, 烏臺詩案) was a trial on charges including treason, or, lèse majesté (Sung Criminal Code, Article 122: "Denouncing the Imperial Chariot") that occurred in the year 1079 (during the Song dynasty) era of China (960–1279). <P2-S1>  "Crow Terrace" refers to the imperial Office of the Censorate (御史臺), which prosecuted the case, a nickname. <P2-S2>  The most prominent figure of the numerous accused parties was the official and artist Su Shi (1037 – 1101), whose works of poetry were produced in court as evidence against him. <P2-S3>  Of the several tens or dozens accused, the most prominent figure was the remarkable artist and political leader Su Shi, whose works of poetry were produced as a key part of the evidence against him. <P2-S4>  The Crow Terrace Poetry Trial was a major landmark in the struggle for free speech, in medieval China; and, as the outcome of the judicial proceedings resulted in Su Shi's conviction and sentence to exile, as well as the conviction and sentencing to various punishments of over 30 other individuals (some or many of whom were let off with fines and reprimands), the Crow Terrace Poetry Trial had the significant effect of dampening subsequent creative expression and set a major negative precedent for freedom of speech, at least for the remainder of Song Dynasty China. <P2-S5>  Besides the significance of the Crow Terrace Poetry Trial for Su Shi and poetry, it is also a rather remarkably well-documented instance of a medieval Chinese literary prosecution, with surviving copies of indictments, arguments, case disposition; not to mention numerous of Su Shi's poems, which were entered as evidence. <SEP> <P3-S0> Steven Randall "Randy" Jackson (born October 29, 1961) is an American singer-songwriter, musician and dancer. <P3-S1>  Jackson is best known as a former member of his family band, The Jacksons. <P3-S2>  Jackson was the youngest son and the second youngest Jackson sibling before his sister Janet Jackson was born.
