YouTube is the most popular video sharing site where you find videos shared by common users to big organizations sharing their training materials, demos and live casts. Lets an assume an organization wants to upload training/product demo videos to YouTube and embed them on their corporate website. Would not it be nice if they can hide the YouTube logo from the embedded videos? Definitely Yes.
To remove the YouTube logo you need to do a small change to the embed script before using it on your site. Add the flag modestbranding=1 as shown in the script below
Here is a YouTube video embedded in this post without the logo.
The catch is when logo is hidden the player shows text YouTube as a text overlay at top right corner when you hover the mouse. Hope Google will let us hide even that in the near future.
