Parts of fired FBI Director James Comey's Thursday Senate testimony were seen by 89 million people on Facebook. Nielsen estimates 19.5 million people saw it on live television.
Why this matters: The high-profile Congressional hearing (McCarthy, Iran-Contra, Anita-Hill) used to be prime spots for television. Now those audiences are shifting online. In addition to Facebook, 2.7 million people watched it on Twitter's Bloomberg co-branded livestream. (One caveat: a Facebook view can be as short as 3 seconds, so a direct comparison to TV ratings is inexact.)
