The 54-65 years old, a new segment for online marketing?

I recently saw that the 54-65 years old people are more and more represented on social media.
According to a study, their rate is generally between 8 and 10% on the most reputaed networks and reach a 12% rate on Facebook.

I see that there are specialized advertising agencies but not digital.

Do you have examples of digital campaign specifically targeting this emerging segment?

I think that it is time to think about and to start to sell it to our clients.

What do you think?
