Note the opening five words:
"Advertising is a marketing communication..."
Your tone is unnecessary and off-target. The above quote from line one is exactly what I said.
You don't just wake up, roll out of bed, and advertise. Well, you can but waste a ton of money. In any case, that message needs to be crafted. That's marketing. Advertising is how you disseminate that "plan."
Logo - marketing, not advertising.
Style guide - marketing, not advertising.
Positioning of the brand - marketing, not advertising.
And so on.
Marketing is the plan. How you wish take and place your brand / product to market. Advertising is the communication of that to thd market. Advertising is what happens when the meeting ends and its time to engage the market.
Marketing = what we have to say and who we wish to say it to.
Advertising = Got it. Let's see what tools we have to best make that happen.
No dreams. That is how it happens.
