Desafortunadamente o Infortunadamente

Question

I need to say something along the lines of "unfortunately, you can find this commercial on many channels." So, my question is, should I use "desafortunadamente" or "infortunadamente?"

Answer 1

I have heard desafortunadamente, far far more, of those two, but that may be regional.

Also, por desgracia, which I believe I hear between those two, in frequency.
