A series of experiments for the purpose of learning how to change people’s minds for them using a variety of means, most famously (but not only) chemicals. Since we don’t know what other directions the research may have gone in or even if they ever stopped (why would they), whether you think it succeeded depends on what they looked into and how ambitious their goals were. Personally, I doubt they have mind control chemicals or anything like that, but I bet they learned a lot about mass media.
