I would say at the end of the year, will be aired a retrospective report on the events of the year/facts that happened along the year.
But then, I am talking about the usual broadcasting that TV channels in Brazil run at the end of the year. Chances are that I am thinking something and the question was about something else. If so, let us know, please.
By the way, by "on the events of the year" I mean, the most important events. Before somebody says that "the events of the year." would take all the year to be replayed.
