An 18-second clip of a young man standing in front of an elephant enclosure at San Diego Zoo in California, describing their 鈥渞eally long trunks鈥� was the first video to be posted onto YouTube in April 2005.

It was uploaded by co-founder Jawed Karim, who with friends Chad Hurley and Steve Chen, cooked up the idea for the video-sharing service while working together at PayPal.

Twenty years later, it is now available in 100 countries and has almost three billion users around the world.

Produced and presented by Reena Stanton-Sharma using archive interviews.

Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past. We take you to the events that have shaped our world through the eyes of the people who were there. For nine minutes every day, we take you back in time and all over the world, to examine wars, coups, scientific discoveries, cultural moments and much more.

Recent episodes explore everything from football in Brazil, the history of the 鈥業ndian Titanic鈥� and the invention of air fryers, to Public Enemy鈥檚 Fight The Power, subway art and the political crisis in Georgia. We look at the lives of some of the most famous leaders, artists, scientists and personalities in history, including: visionary architect Antoni Gaudi and the design of the Sagrada Familia; Michael Jordan and his bespoke Nike trainers; Princess Diana at the Taj Mahal; and G枚rel Hanser, manager of legendary Swedish pop band Abba on the influence they鈥檝e had on the music industry. You can learn all about fascinating and surprising stories, such as the time an Iraqi journalist hurled his shoes at the President of the United States in protest of America鈥檚 occupation of Iraq; the creation of the Hollywood commercial that changed advertising forever; and the ascent of the first Aboriginal MP.
