Nielsen is out with their Millennials on Millennials report and you don't have to be a brain surgeon to know how to reach Millennials.

You go to the internet. 

The report shows that digital news reaches 88% of Millennials in a month, while it only reaches about 80% of adults 38 and older. TV news reaches less than two-thirds of Millennials, but reaches 90% of the older demographic. Despite radio having the lowest monthly reach among Millennials, at 23%, their time spent with radio actually exceeds digital and TV news among the demographic—nine hours per month for radio, compared with three hours, and six hours for digital and TV news, respectively.   

The good news for TV?

Millennials are dramatically influenced to tune in to TV during breaking news moments, even more so than adults 38 and older.When looking at monthly reach trended for Millennials, there are spikes in both TV and digital news during special events, such as the 2016 Presidential Election and the Presidential Inauguration in January 2017. Millennials continue to look toward digital news during these events but also tune into TV for supplemental information.
