What is a keynote presentation?

Technically, a keynote address is “a policy, speech, or idea is the main theme of it or the part of it that is emphasized the most.” However, most people consider a keynote the main presentation to the entire conference (opposed to smaller breakout sessions). A keynote presentation is generally on a podium or stage with screens flanking it and it is given to large audiences. Keynote speakers are held in high regard because they usually present often as a highly regarded person and many keynote speakers are professional speakers that do 100-250 paid presentations a year around a central theme (usually related to their book).
