Final answer:
The nine advertisers are engaging in a A) sponsorship type of advertising arrangement, where they underwrite television programs in exchange for commercial spots, capitalizing on targeted advertising and stronger brand presence amidst today's attention economy.
Step-by-step explanation:
The consortium of nine major advertisers joining Television Production Partners is using a sponsorship type of advertising arrangement. In this model, the companies underwrite television programs in exchange for a portion of the commercial spots during the shows. This type of arrangement allows for a close association with the content and enables them to target their advertising to the appropriate audience using sophisticated viewer data from network and cable television companies. To elaborate, this sponsorship strategy offers benefits such as a stronger brand presence and the ability to influence the creative process. The partnership between advertisers and television productions is not entirely new; it has its roots in the early days of television. However, in today's fragmented media landscape, sponsorship agreements have become increasingly significant as a way for advertisers to stand out in an attention economy characterized by multiple platforms and consumer control over media consumption.
