Over the course of a comedy career spawning over three decades and counting, Jerry Seinfeld has built a vast repository of stand-up material. But until today, he has never been truly master of his domain. In the online sense at least.

Today marks the debut of his website, JerrySeinfeld.com, an online home for videos of nearly every recorded comedy performance delivered by the entertainer. There are more than 1,000 clips of his stand-up act and comedic interviews. One segment dates to 1977 when Seinfeld, wearing glasses and wide lapels and speaking with a distinct New York accent, made his television debut on "Celebrity Cabaret." The others range from his first network television appearance on a 1981 broadcast of "The Tonight Show Starring Johnny Carson," to the present. Each day the web page will offer only three of these videos, chosen by Seinfeld, a strategy he calls "portion control."
