CNN has launched a multi-month network initiative to mark the most iconic moments and news events of the past 30 years. Titled CNN30: WERE YOU THERE? CNN is asking viewers from around the world to submit their photos, memories, videos via iReport, the network’s user-generated news community, online or directly via the CNN international iPhone app. Viewers are together invited to help build an interactive timeline on CNN.com at www.cnn.com/30 of the past three decades, sharing their recollections and any archival footage, pictures and more. The best of these submissions will be featured in a half-hour special program premiering on CNN International on October 23 at 8:30pm (HKT).
