We are are starting to post video on our site and just posted our first one--a small video window where the user clicks and it opens into a new window. I have been told by a fellow colleague that this is circa 1990s and the video should play in the same window.

Before I have our developers change this, I'd like some consensus that this is actually best practice because I am not sure. Can anyone share their experience or point to any sites/resources? Thanks!
