quotes a York University study. Their work shows pharmaceutical companies spend almost twice as much on advertising as R&D. Frankly, I would expect that ratio to be reversed, as high-tech R&D costs are, well, high. (I have first-hand experience, having worked in similar R&D and piloting operations in years past.)
Your extravagant claim is "$100 million" for R&D and "billions" for advertising, which is a ratio of 1:20 or less. The NYU study says the ratio is not even as low as 1:2. This is why your statements lack credibility. They don't match up with published facts.
