Jumpcut was a company Yahoo acquired in 2006. It let users edit video clips right in their browser, as well as host them when they were through.
Jumpcut's death is similar to that of the long, drawn-out ones you see in movies. The kill shot was actually fired back in December of 2008 when Yahoo began to limit users from uploading new clips to the video editing service. However Yahoo went for an extremity instead of the vital organs, extending the life of the site for four months with little or no explanation on when it would be put out to pasture. Then, in mid-April the company announced that it was indeed shutting down the site, which it kept open for another two months. The site was officially put to rest on June 15, 2009.
