The 1990s had remarkable highs and lows: Technology paved the way for a digital world, and the ranks of billionaires grew fast. But the Columbine massacre, al-Qaida threat, and Clinton scandals also happened. On the heels of its popular miniseries deconstructing the 1980s, National Geographic Channel delves into 10 years when the Web was wide open but before global terror hit hard. "The '90s: The Last Great Decade?" features 120 original interviews -- from unsung heroes of riveting stories, to notables in many fields -- and memorable clips of a time between the end of the Cold War and the approaching War on Terror.
