I've met several old school marketer in the past few years and it's the words they used that gave it away. How old? Older than my parents even! They are from a generation where marketing is pretty much just advertising.
- A&P = Advertising & Promotion
- MARCOM = MARketing COMmunication
If you heard any old geezers said this then they are the OG marketers born before Malayan independence. It was a small exclusive world back then which only big companies could afford to advertise.
