An HTML tag created in earlier versions of Netscape to provide blinking text analogous to that seen in ANSI art on BBS's back in the 1980's. To use this tag is widely known as the worst stylistic decision a web designer could ever make, even worse than specifying Times New Roman as your default font or hard-coding your table widths in pixels, not percentages. Blinking text is hard to read, is not supported evenly across all platforms, and is generally annoying. Anyone who uses this tag deserves to die. I myself have used it to make exactly one word blink. I beg your forgiveness.
