It’s BernhardMod BT, a nice font made great by the fact that it was used in most of the original Twilight Zone episodes. This is a TrueType font, suitable in just about any computer (Mac or Windows, for two examples). You can download it from here:
One caveat if you plan to use this font on a website: you cannot count on your audience having the font. That’s why the font does not appear much on the current version of our website. If youb really, really want to use the font on a web page here’s how: create the BernhardMod BT banners in a word processor and then use a screen shot to convert them to .jpg or .gif graphics when you use them on the web pages. It’s also an excellent way to display bigger letters than HTML normally allows.
