I think a majority of the money was divided between 3 groups: toxic funding, lawyers, and marketers, (well, the MM's, too, but that's a given). Investor awareness marketing can be put under Toxic funding I guess, since marketing is one requirement of the funding.
Early on, I think things like the comedy radio show promotion was a company decision. Things that were paid for with shares. Later on when the CD was full swing promotions were paid for with cash - something the company didn't have but if a requirement of taking a tranche is paid promotion the only way out of it is not taking the tranche.
These promotions could cost $20K+. There was a little transparency at the time that allowed me to see a bit about what was going on. That 3 minute Youtube chart video of some guy talking about the technicals cost something like $700.
This can all be seen in the Q's, but isn't broken down line item, so easy to overlook.
