Who sponsored Star Trek in the 1960s?

Does anyone have the facts on who the corporate sponsors of Star Trek were during its original run on NBC? I watched the series faithfully from the beginning, but I don't remember. It seemed that this wouldn't be hard to track down online, but I didn't find the information I wanted. It's just a matter of idle curiosity.

I think Desilu produced Star Trek. But who placed ads with NBC during that hour each week?
