The FastCompany website has published an infographic that is useful to anyone involved in the launch of a new product.
The infographic shows the sales volumes in the launch year of new Apple products, from 1976 to 2015:.

The infographics in turn is inspired by an article in the Wall Street Journal highlighting the market difficulties of Apple Watch.
But what I want to emphasize here is rather the growth trend of volumes in Apple launches.
It’s as if there was some kind of combined effect, so each launch is also a seed for the next launch, and so on.
As if it created a hard core for the next launch.
I exhort you to reflect on the two paragraphs above because they contain a big secret.
This model means that even a not so successful product (Apple Watch) still sold twice as many units as the first iPhone!
It’s not just about the products, then: there’s also a marketing strategy behind it. Or rather, a strategy for launching a new product.
And what can we do as ordinary people, given that we are not Apple?
I premise that we aren’t the Italian gurus of the online launch of new products (I will soon introduce you to those who can boast of this title).
But when talking about launching a traditional product in a traditional market, and when other media and other components are involved apart from the web (eg: the sales network), we are experts in the field. First within multinational companies, then for ourselves.
We studied more than one technique…
… we tested them all here in Italy…
…we took away everything that didn’t work…
… we have added our specialisation in B2B sales…
… and so the model for launching a new product in traditional business-to-business markets came out.
We sell this know-how as a service.
And you can deepen the potential for your business without investing a penny.
Here’s how.
If you have a new product to launch, write to me describing your case.
I’ll answer personally by email telling you if we can help, and what investment you could go to (between our service and “gasoline” for other resources needed to run the launch).
Then, you know, one thing leads to another.
I only ask you this: if you think you can launch your new product without any investment, don’t submit the case because we would both only waste time.
Here’s the form, please give me as much information as possible to understand the situation:
