In a co-driver situation, unless the two brands stand for comparable quality, the association might tarnish the more prestigious brand. When Marriott, a premium hotel name, endorses Courtyard, the risk to Marriott's status and perceived quality standards is reduced because it is an endorser. If Marriott had instead been a co-driver (meaning in part that its name would be just as promi- nent in visual depictions) the Marriott brand would have been perceived to have been stretched downward and its perceived quality as a product brand would therefore be in greater jeopardy.
