Coca-Cola created the advertisements?
Yes. Now rewrite that sentence, using Coca Cola as the subject of the verb created.
The sentence says the ads were created by Coca-Cola, doesn't it? So, how would you rewrite in an active voice?
Coco-Cola has created numerous Christmas advertisements,depicting a jolly,red -suited Santa Claus holding a Coca-Cola bottle.
Great! :-)
btw -- omit the comma after advertisements.
