To this day I still think Principles of Marketing by Philip Kotler it's the best book to give you as close to foundational knowledge you can get, and you can go from there to get depth further into the disciplines that compose it - like advertising, distribution, etc. Some people criticize Kotler because he "only studied marketing", didn't practice it. I don't see anything wrong with that, specially after being adopted as a standard for decades.
