I have 30, 45 & 60 second commercials. I read recently that a hook or tagline, is not as important as they used to think, but I disagree. I think anything extra that makes you stand out is good.
I know a man who tells his company name, that he does web development & says, "You all know what that means." He then proceeds to tell a joke, instead of a commercial. He even keeps track of where he has told which joke. And of course, they are all above the board jokes.
How do you fix a broken tomato?
