Describe the methods used to measure sponsorship activities

What will be an ideal response?

It's a challenge to measure the success of events. The supply-side measurement method focuses on potential exposure to the brand by assessing the extent of media coverage, and the demand-side method focuses on exposure reported by consumers. Supply-side methods approximate the amount of time or space devoted to media coverage of an event, for example, the number of seconds the brand is clearly visible on a television screen or the column inches of press clippings that mention it. These potential "impressions" translate into a value equivalent to the dollar cost of actually advertising in the particular media vehicle. Although supply-side exposure methods provide quantifiable measures, equating media coverage with advertising exposure ignores the content of the respective communications. The advertiser uses media space and time to communicate a strategically designed message. Media coverage and telecasts only expose the brand and don't necessarily embellish its meaning in any direct way. Although some public relations professionals maintain that positive editorial coverage can be worth 5 to 10 times the equivalent advertising value, sponsorship rarely provides such favorable treatment.
The demand-side method identifies the effect sponsorship has on consumers' brand knowledge. Marketers can survey event spectators to measure recall of the event as well as resulting attitudes and intentions toward the sponsor.
