A large news company wants to develop a test that will show up in their marketing-mix model. The goal is to identify the effect of a new media channel during a one-week test conducted across many digital channels as well as TV. They are a national newspaper, so a significant number of conversions come organically on a weekly basis.

The company typically spends $275,000 per week on media, and plans to spend an additional $5,000 on this test, for a total weekly spend of $280,000. The company typically spreads the $275,000 across three digital channels and a mid-sized TV buy.

Which action should be taken to ensure the feasibility of the test showing up in the model?

A. Remove TV spending from the campaign

B. Increase the number of channels being used

C. Increase the duration of the test-period

D. Increase the overall advertising spend across the target channel
