According to a recent post on YouTube’s blog, the YouTube logo at the bottom of an embedded video is now optional. So, you now can embed a YouTube video on your Web site without the YouTube branding in the control bar.
The blog post, written by Software Engineer Kevin Wilson, states, “Many of you have asked us for a version of the YouTube player without a YouTube logo, so the video plays without any branding nearby.” To remove the YouTube logo, you added the following string at the end of the embed code:
Do note that the branding is modest according to this string. A small “YouTube” text still appears at the top right when you hover over a paused video, but this is far less noticeable than the YouTube brand.
