TED began in 1984 as a conference bringing together people from technology, entertainment, and design. It has since grown into a global platform for short, powerful talks on almost every subject imaginable: science, psychology, business, art, activism, and personal stories. Talks are typically under 18 minutes, which makes them easy to fit into a break. The speakers range from Nobel laureates and CEOs to unknown individuals with a remarkable experience to share. The format forces clarity, and many talks have become reference points in classrooms and offices.

The website hosts a huge archive with subtitles in dozens of languages, transcripts, and curated playlists. You can filter by topic, length, or popularity. TED also runs TEDx events independently organized around the world, and its podcasts and newsletters extend the content beyond video. For anyone who wants to learn something new or see a subject from a different angle, it is one of the most accessible and consistently interesting places online.
