One specific commercial that you can look at the use of conditioning in is the intel commercial linked below.  This commercial doesn't even advertise a specific product and is using conditioning specifically to link a feeling to the brand name.  Two examples of conditioning are the inclusion of a diverse group of workers all dressed in relatively hip clothes, suggesting an image of hip young people working for Intel and the color themes of light blue and white creating an atmosphere of modernity, again meant to connect that feeling with the Intel brand.
