I NEVER put the business name in the ad. It often is part of the display URL, but not title or description. The reason is that people are not interested in who (the company), they are interested in what you are offering them, the product's or service's features and benefits. Putting the company name in the ad is wasted space.
For the clients I manage, we often include the company name in search ads, and ALWAYS include it in ads for the content network, both text and banners. We want the clicks but we also want the branding exposure.
In my own AdWords campaigns which promote affiliate products, I rarely mention the company anywhere but in the URL.
