NBC True CRMZ is an American digital subchannel network, airing true crime documentary programming.
The channel, originally known as LX, later LX News and NBC LX Home, is a brand for original home and lifestyle content, originally for the NBCUniversal-owned television stations. LX is short for Local X, with the "X" standing for "exponential". NBC LX Home is a part of the station group's multicast division LXTV, led by senior vice president Meredith McGinn, content strategy vice president Matt Goldberg and managing editor Meagan Harris.
In July 2024, NBC LX Home on over-the-air television stations was rebranded as NBC American Crimes, a format airing true crime programming. A new iteration of NBC LX Home launched on free ad-supported streaming television (FAST) shortly afterwards. In September 2025, the channel rebranded to its current moniker, retaining the American Crimes branding on its FAST channel counterpart.
The channel's predecessor, NBCUniversal's previous news and lifestyle multicast network NBC Nonstop (now known as Cozi TV), was launched in 2009 on its owned and operated station group, mostly on NBC O&O affiliates that previously carried NBC Weather Plus. Its programming included core shows from LXTV.
LX content featured longform content, a switch from prior NBCUniversal efforts at NBC News Now with Briefly and Snapchat news show Stay Tuned, created to reach Generation Z and millennials. With the broadcast network and streaming television channel, there were two live programming blocks (7-10 AM and PM) of three hour daily newscasts produced at KXAS. LX programming originally came from station groups and the owned and separately operated LXTV Productions, with licensed additional content to fill out the day. The additional content came from Jukin Media, Tastemade and The Dodo. The main newscast when launched was two hours long.
NBCU stations' desire to reach younger audiences led to the creation of the LX content brand. On September 23, 2019, the station group launched its LX news digitally initially on YouTube, its website and social media. LX was launched as a live-streaming channel and multicast over-the-air network in May 2020.
In August 2023, LX was rebranded from LX News to NBC LX Home as it transitioned from a news format to a home and lifestyle format.
In July 2024, NBC LX Home was rebranded as NBC American Crimes, and a new iteration of NBC LX Home launched on free ad-supported streaming television afterwards.
