Katie Couric looked to Facebook, with its one billion users and status as the world's most popular social media platform, to find out what people were really talking about in 2012. In a television exclusive, Couric is dedicating the "12.12.12" episode of her nationally syndicated daytime talk show, "Katie," to the year that was, reviewing the biggest moments and hottest conversations as measured by Facebook. The episode will air WEDNESDAY, DECEMBER 12 (check local listings/ or www.katiecouric.com).

Facebook's most popular stories are determined by the top shares and conversations among its users, which are being sharing exclusively with "Katie." Facebook Director of Design Kate Aronowitz will join Couric to talk through how the online giant measures particular moments in time, and how different people and events captured the attention of this one billion member online community. Tapping into Facebook's "Year in Review," which allows users to see their top moments of the year, Couric will reveal how people on Facebook are interacting and the things they cared about most during 2012. From the photo that got more "likes" than any other in Facebook history to how the shocking news about the death of Whitney Houston unfolded online, Couric shows what it was that connected people, and how they shared the biggest moments of the year.

Throughout the show, Couric will be joined by friends and commentators to weigh in on everything from the pop cultural phenomena to the people we loved and lost during the past year. Guests will include Luke Russert in a look back on news events, author and comedienne Ali Wentworth, CBS Sunday Morning correspondent Mo Rocca, Billboard Editor-in-Chief Joe Levy and E! News' Alicia Quarles on what was hot – and not -- in television, music, movies and more. Plus, meet the inspiring heroes whose stories went viral, find out what touched Couric the most in 2012, and see YouTube sensation Pentatonix perform a medley of the year's most popular songs in "Katie's" studio.
