"When we released Netscape Navigator 1.0 we did not document the blink functionality in any way, and for a while all was quiet. Then somewhere, somehow the arcane knowledge of blinking leaked into the real world and suddenly everything was blinking. "Look here", "buy this", "check this out", all blinking. Large advertisements blinking in all their glory. It was a lot like Las Vegas, except it was on my screen, with no way of turning it off.
In the end, much was said, most of it in the form of flaming posts to various discussion boards, and the <blink> tag will probably be remembered as the most hated of all HTML tags. I would like to publicly state that at no time did I actually write code or even seriously advocate for the <blink> tag. It is true that I put forth the initial inspiration, but it really was merely a thought experiment. I am not going to name any names of the people who coded the dastardly deed, if they wish to step forward, they will need to do it themselves."

Also, firefox used to have an option in about:config to allow the blink tag to be turned off.
what about <marquee>?
