To make this site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.
A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size, and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.
They all expire within a few hours from the first access or when you leave the website.
The only cookie we might store (for a period of 4 months maximum) sets the preference for the chosen language of browsing.
By accepting this cookie to be installed, you agree on having the cookie saved on your computer.
By refusing it, it will expire when you leave the website and no information will be saved.
Enabling this cookie is not strictly necessary for the website to work but it will save you from setting the language preference once again when you come back to TED website.
These cookies are not used for any purpose other than those described here.
You can control and/or delete cookies as you wish – for details, see AllAboutCookies.org. You can delete all cookies that are already on your computer and you can set most browsers to prevent them from being placed. If you do this, however, you may have to manually adjust some preferences every time you visit a site and some services and functionalities may not work.
