Which of the following is NOT considered when constructing a media planning timeline?

When constructing a media planning timeline, one important aspect is understanding the relationship between the media and creative elements. The media planning timeline primarily focuses on aspects like scheduling, budget allocation, and resource availability.

Vendor availability is crucial because it determines when and how media can be purchased and placed; if a vendor is fully booked or unavailable, it can impact the entire media strategy. Media cost estimates are also a vital consideration since they directly affect budgeting and planning decisions. Audience research findings inform target demographics and optimal media placements, guiding the decision on when and where to advertise to achieve the best results.

While the scope of the creative team is important to overall campaign success, it does not typically influence the media planning timeline directly. Creative processes, such as the design and production of materials, may have their own timelines that are somewhat separate from media placement strategies. Thus, the creative team's scope is not a fundamental component considered in constructing a media planning timeline compared to the other factors listed.
