The “Open Happiness” message, the 2009 Coca-Cola marketing campaign, was seen in stores,
on billboards, and in television and print advertisements along with digital and music
components—including a single by Janelle Monae covering the 1980 song, “Are You Getting
Enough Happiness?”

First you need to ask yourself WHO did the seeing.

Once you figure that out, you'll be ready to revise this sentence.

Drivers saw the billboards?

Did people in stores, those who saw TV and print ads, etc., NOT have exposure to the campaign?

To change passive voice sentences to active voice sentences, follow these steps:

1. Identify the subject of the sentence.
2. Identify the verb.

Here are the active voice versions of the passive sentences:

1. Stores, billboards, and television and print advertisements, along with digital and music components, prominently displayed the "Open Happiness" message, the 2009 Coca-Cola marketing campaign.
(Note: In this case, it is not clear who specifically displayed the message, so the sentence refers to the display itself.)

2. Janelle Monae covered the 1980 song "Are You Getting Enough Happiness?" as part of the 2009 Coca-Cola marketing campaign, featuring the "Open Happiness" message.
