What does a publicist do exactly?

Question

i have a small understanding please explain in detail

Answer 1

He/She "spins".

They handle all the p.r. for celebs, hoping to make them look good, or play down bad publicity.

That's a concise, but precise explanation.

Answer 2

They make certain that everything written or said puts their client in a good light, reshapes their image to what ever they desire, handles the bad press that their clients get and spin it to their clients advantage. When all you ever read and see about someone is how great and fine people they are, they become everyones idol.
