I wonder if Les Bauer had to pay for its product to be used in the episode, or if they simply had to give permission for its use.
It seems a pretty safe bet the company did. If it was mentioned repeatedly, it probably cost a nice chunk of change.
Payment for product placement, either by mention in the dialogue or just having the item shown lying around or being used, is used to underwrite a lot of cost in making movies. I expect it's done in TV as well.
