ABC News this morning apologized for describing as “long lost” the “never before seen” deposition tapes of OJ Simpson made for his civil trial over the murders of his former wife and her friend, on which the news division claimed to have an “exclusive” look. In an online version of its report, ABC News added this note:

“Editor’s Note: This story has been adjusted to correct a previous inaccuracy. We were wrongly under the impression these deposition tapes were exclusive and had not aired before at length. We learned this morning portions did air 15 years ago. We apologize for the mistake.”

But before the adjustment was made, ABC News’s Good Morning America had plugged tonight’s season debut of 20/20 featuring a look at “long lost” deposition tapes of OJ Simpson that were made for his civil trial over the murders of ex-wife Nicole Brown Simpson and her friend Ron Goldman.

“For the first time we hear Simpson’s chilling testimony about his relationship with his ex-wife, Nicole,” said George Stephanopoulos, calling it an exclusive look at tapes “never seen before.”

After which, 20/20 anchor Elizabeth Vargas noted the newsmag’s look at the tapes is a plug for two documentaries – A&E’s documentary OJ Speaks: The Hidden Tapes, premiering October 1, and the LMN documentary The Secret Tapes of the OJ Case: The Untold Story, premiering September 30 -– both A&E and LMN being partly owned by ABC-parent Disney.

Those never before seen tapes had been broadcast on NBC’s Dateline 15 years ago, and again in 2004, and again just last year.” As reporters noting a Dateline tweet…

…and doing basic Nexis searches, began reporting this morning.

ABC News eventually added its correction note, though its online report still insisted they are “rarely seen deposition tapes” in its headline. The news division did not say whether A&E and/or LMN plans to correct the names of their docus.
