Product Placement

Alright, trivia time. My current corporate family has one of it's logos appear, but it is not mentioned, in all of the last 3 episodes of The West Wing. Comment or email me with specifics and I'll let you know if you're right.

I don't know if it's actually paid product placement, but it seems odd to me that the item in question shows up in all 3 episodes with the logo readable at least once and recognizable more often.
