Companies really like online advertising because you can track and measure important things like ROI, and such, so much more easily than say, television ads. Imagine you are a public company, okay fine, an OTC listing, you start ramping up that ROI - investors catch on, and your share price rockets up. Sounds like a good plan, right? What if you cut out some of those intermediate steps? Sounds even better, right?
Just like sending your own email stock tip spam, without the silly CAN-SPAM stuff.
