Know-How Exchange : Other

Your question is somewhat confusing, and quite broad.

Confusing because you ask about channels first, then ask about the 4Ps in whole. Channels are one of the 4Ps (Place).

Second broad, because the 4s are generally covered in college classes using at least a whole text book. I am not sure an article would cover in any sort of detail to be of use. Instead I would recommend you get a good marketing book or text book.

That all said, here are some articles:

In addition, sometimes people use the 7Ps when they talk about service marketing.

Hi Goldbyrd,

Your question is as Peter says confusing.

To make sure you get exactly what you need, why don't you just go to www.google.com and enter your search phrase(s)?

There are thousands of references for you there and you can find one that fits your need perfectly.
