advertising arms race. if you're a startup with millions in ad spend and a mandate to spend it in a couple years, how do you spend these millions? the same way

advertising arms race. if you're a startup with millions in ad spend and a mandate to spend it in a couple years, how do you spend these millions? the same way all the other startups do, by dumping into google, instagram (fb), amazon. makes me wonder how many of these same VC's also own large positions in said advertising companies?
