So... Copywriting is essentionally coming up with slogans?

I don't mean to offend anyone in this industry but based on what I've read (online not in books) about copywriting, it seems to be coming up with slogans and catch phrases. Am I close or am I dead wrong? If I'm wrong, can someone please explain it to me?
