Watch The Whole Story with Anderson Cooper

CNN Anchor Anderson Cooper returns with a special one-on-one interview with Microsoft founder and philanthropist Bill Gates. In this wide-ranging sit-down, Gates tells Cooper about the moments that shaped him, from his childhood in Seattle to co-founding Microsoft at age 20, fueling the personal computer revolution that has become part of our everyday lives. Gates unpacks the stories revealed in his new book Source Code: The Origin Story of Bill Gates. Gates speaks with emotion about the influence of his parents on his life and his unique way of thinking as a child. He visits his alma mater, Lakeside School, an elite all-boys private institute at the time of Gates's enrollment, and a place he credits with his transformation into an engaged student and fanatical computer programmer by the age of 13. It would also be the place where he would befriend his Microsoft co-founder, Paul Allen. After reflecting on his past, Gates discusses his thoughts on the future, including his recent meeting with President Donald Trump, Elon Musk intervening with USAID, and the potential impact of artificial intelligence.

CNN Anchor and National Correspondent Erica Hill takes a deep dive into the future of Venice, a city threatened by rising sea levels and the millions of tourists desperate to visit while they still can. Much of the world fears that climate change and rising sea levels will soon sink the ancient city of Venice, a misconception that is causing millions of tourists to visit each year while they still can. In "Saving Venice," Hill discovers that the more imminent threat to Venetians' way of life is this overwhelming flood of tourists, transforming the city's culture, housing and local economy. Hill speaks with a collective of locals interested in promoting a more ethical tourism industry with respect for Venice's unique and delicate environment. She learns about the innovative ways a new generation of Venetians are working to preserve the city's traditions, mitigate the effects of climate change, and taper the city's dependance on massive amounts of tourists. "The rich history of Venice is one of innovation, evolution and entrepreneurship," said Hill. "That legacy is being tested now more than ever, but there are sustainable, thoughtful solutions to save this beautiful city, its culture, and most importantly, its community. With unique access to the Venice many visitors don't see, I am hopeful this hour will introduce audiences to a city - and a story - that is also a critical wake-up call for others around the world." The episode features interviews with local Venetian restauranteurs, artisans, oceanographers, city planners and more. Hill even gets a rowing lesson in the canals of Venice from a competitive rower whose family has been competing in the city for generations.

CNN Senior Investigative Correspondent Kyung Lah presents an in-depth look at the unusual star-making K-Pop industry in South Korea. K-Pop idol bands have fan bases all over the globe, hugely popular musicians and songs originating from South Korea. But these bands are molded and created in a way unlike anything else in the music industry. Aspiring young stars take on rigorous vocal, dance and fitness training from early morning to late at night, some even leaving school and living in dorms away from their families. In "K-Pop: A Star is Made" Lah embeds in the strenuous training process of seven aspiring K-Pop stars in a small studio in the heart of Seoul, South Korea when they are just one week away from auditioning for the studio's premiere idol group. "As a Korean American growing up in Chicago, I never imagined my native language would be streamed across platforms in the US as a multi-billion-dollar industry," said Lah. "It still shocks me to this day. What I wanted CNN's audience is to see and experience how this happened, through the intimacy of the struggle of the K-pop trainees you'll meet in our hour. They're more than perfect young men and women of the TikTok era — they're utterly human, some as young as 14, and as vulnerable as the young fans who listen to them." The episode features interviews with Amber Liu, Megan Moon and Min who talk about the global impact of this explosive industry, which also comes with international scrutiny for its stars. Lah also speaks with the trainees about the pressure to maintain a certain appearance, and how extreme dieting and plastic surgery are common amongst K-Pop hopefuls.
