Investigation Discovery network’s JonBenet: An American Murder Mystery is the most-watched series in the history of the Discovery Communications network, averaging 2.6M viewers and 1.1M in the news demographic across its three-night premiere, according to L+3 stats.

Investigation Discovery’s project from Weinstein Television, American Media, Inc. and Jupiter Entertainment, aired Monday through Wednesday of last week at 10 PM. It peaked with Episode 2, which topped ad-supported cable for the night with 2.8M viewers and 1.3M in the 25-54 age bracket. In total, the series was sampled by about 11M viewers across its three nights.

“This story is as compelling as any movie I’ve seen and I am delighted with its success on ID,” The Weinstein Company co-chairman Harvey Weinstein said of the numbers.

ID’s not the only network enjoying the country’s fascination with the unsolved murder of a six-year-old girl in Boulder, Colorado on the 20th anniversary of her death. Part 1 of CBS’s The Case of: JonBenet Ramsey clocked 10.3M viewers on Sunday, giving the Emmy Awards a run for its money, though the numbers are subject to revision owing to a football delay in eastern time zones.
