French to English Marketing Internet, e-Commerce Advertising campaign

This comes from a presentation by an advertising company of a past advertising campaign, as an example of what they are capable of.

The campaign took place across various media with a view to connecting with, and boosting donations to, a particular charitable organisation. It included a twitter bot that responded to tweets mentioning the charity, offering more information, emphasizing the need for donations etc.

At this point in the presentation they are highlighting the timing of various initiatives (release of videos, TV commercials, etc.) and under the twitter symbol there is:

"Amplification media de 4 temps forts conversationnels".

I imagine this means that they initiated four periods of intense twitter activity. Any comments welcome.
