I wish to find out the name of font used for the television show Duck Dynasty. Does anyone know? It looks very familiar.

ITC Newtext  Vorgeschlagen von pilaster

It's Copperplate Gothic.

Looks more like…

Is there a free one?

Nope. 'Tis a commercial product, like a automobile (only less expensive) or a burger (only more expensive, unless it's a REALLY expensive burger) so if you want to use it, buy it.
Vast amounts of possible alternatives here…

No, it looks like Copperplate Gothic, which is free, and also on Word.

1. bravo and thanks for the perfect matching suggestion, it's definitely thousand of times better
2. coming with Word doesn't mean it's free. It's a commercial font and downloading from that web you linked it's illegal (link changed, btw)

You're an idiot. The proper typeface is ITC Newtext, and it is a commercial font, not free.
copperplate is similar, but you did not ask for similar, you asked for the exact typeface.
