Looks like "20/20" is about to outpace "Dateline" - which got a big audience for that well-done Whitney Houston perspective last night - with a two hour special this Friday. Here's the network press release, in its entirety:
"A Special Edition of “20/20,” “One Moment in Time: The Life of Whitney Houston,” will take an in-depth look at the voice of the century -- from her record-setting achievements and musical legacy to her rocky personal life and battle with addiction. It will also include Diane Sawyer’s ground-breaking interview done exactly 10 years ago, as well as the latest developments about the superstar’s final days."
Airs Friday on WABC/7 from 9 to 11.
