Just more friendly food for thought... I think your viewer expectations are another flaw in the business plan you need to seriously reconsider. I can see this business model, if it ever gets off the ground for any extended period of time, getting more paid viewers than has happened in the past (which is typically in the hundreds or very low thousands). But 1 million? I think 20,000 might be a more realistic number. Yes, I know it is "world wide", but 1 millions is a pipe dream, at least for years until and if it takes off with a more mainstream audience which seems pretty unlikely. Some tens of thousands is probably the more realistic prediction on the optimistic end. One might argue that it never hurts to shoot for the stars, but if your business model is built on the need to hit those stars, and those stars just aren't realistic, it can only result in a failed business.
Also, don't forget that at the end of the day, all (aside from a few other intangibles to a lesser extent) advertisers/sponsors care about is how much money their advertising/sponsorship dollars makes them on net--not their gross sales which you keep using. Most of the ones you mentioned probably have 2-5% gross margins I would guess, I think they are fairly thin margins in that industry but someone correct me with the accurate figures if you have them. So that 7 million in sales you keep touting may only make them $245,000 (I split the difference and used 3.5% margins here). So spending 7 million to make $245,000 wouldn't make any business sense at all, and if that is the results they end up getting you can be sure they won't be repeating that mistake a second time. Of course that $245,000 doesn't take into account future profits from brand new customers they manage to acquire who end up becoming repeat customers, but just how many people have never tried burger king before, or dominoes pizza, or any of the others? I don't expect they are going to pick up too many brand new customers so their shorter term more immediate profits is going to be the bulk of what they get out of their advertising and they aren't going to be (and certainly won't keep) spending 7 million to make a quarter million, or even 2 million.
