Why in advertising is the long distance prefix "1" typically included with toll-free numbers beginning with 800, but typically omitted from those with other "area codes"? They're all dialed the same...
Also, why are toll-free numbers not usually written in the traditional format (xxx) yyy-zzzz? I mean, I think I remember seeing 1 (800) xxx-yyyy a lot when I was a kid, but that's gone away (yet the 1 remains).
