ABC News released its first promo for Diane Sawyer’s April 24 interview with Bruce Jenner. The 15 seconds of the back of Jenner’s head and shadows — only Sawyer’s well-lit face is featured — promises to reveal “the journey, the decisions, the future.” E!, which did not land the sit-down with its own Kardashian patriarch, made the best of the situation, describing it thusly: “The E! star shares his journey in the 2-hour television special coming to ABC.”

Earlier this week, ABC News made it official, announcing Sawyer would interview Jenner about his transition on April 24 at 9 PM ET. ABC News said the “far-ranging” exclusive interview would air on a special edition of 20/20″ – two hours of  Bruce Jenner – The Interview.

The May sweep begins this year on April 23. The interview with Sawyer will be the first discussion of Jenner’s transition by a major news outlet.

DIANE SAWYERLast month, E! appeared to have hit the pause button on its planned Jenner reality series, in the wake of his recent car accident, but ABC News plowed ahead with  Sawyer’s interview with the Olympic star turned Kardashian-by-marriage. Plans for the ABC News special changed in light of the crash in which a woman was killed when Jenner’s vehicle catapulted hers into oncoming traffic on Pacific Coast Highway. Seven others were injured. ABC News is expected to cover that wreck in Malibu when Sawyer interviews Jenner.

Sawyer, reigning Queen of the Big Get, landed the interview despite Jenner being a home-grown star of NBCUniversal – parent of E! Entertainment, where Jenner is patriarch of that network’s biggest franchise, the Kardashians. Doubly embarrassing for NBCU: Jenner is an Olympic gold medalist, and NBC is the broadcast network of the Olympics.

Sawyer stepped down as anchor of ABC’s World News Tonight in September, saying she would concentrate on big specials and big interviews. Jenner’s first sit-down certainly checks all those boxes and then some.
