Gorilla Campaign, basically you make a video promoting something/someone or promoting them in the beginning of the video. If it's accepted, you can get high cpms on the video for a limited time.
However I have to mention something. I joined Fullscreen (creator x) wanted to do the gorilla campaigns, however, I realized I can't do any of them now because 99% of them require you to record yourself on camera promoting the product/person/channel. I don't want to show my face on camera so I pretty can't do any gorilla campaigns. :/ Just something to consider... but most people don't mind being in front of camera so it won't make a difference.
