Relaunched on August 1, 1999 as VH1 Classic Rock, the channel primarily featured a mainstream rock/adult hits-formatted mix of music videos and concert footage from the 1960s to the 1980s, though it originally included a wider range of genres and time periods. The channel name was quickly changed to VH1 Classic in 2000. The network played only music videos upon launch, but quickly expanded to a varied line-up of music-themed programs. This included themed music video compilation blocks, full-length concerts, music documentaries such as the Classic Albums and Behind the Music series, music-oriented movies, and an original talk show, That Metal Show. They also re-broadcast programs first shown on the main VH1 channel, including Pop-Up Video and I Love the '80s. From January 28 to February 15, 2015, VH1 Classic aired a 24-hour, nineteen-day marathon of Saturday Night Live in celebration of the show's 40th anniversary. As a result, the network broke a previous record for the longest continuous marathon in television history set by FXX's twelve-day marathon of The Simpsons.
As MTV Classic (2016–present)
In July 2016, Viacom announced that on August 1, the 35th anniversary of the original MTV's launch, the network would rebrand as MTV Classic. The channel's programming continues to focus on classic music videos and programming, but skews more towards from the 1980s, 1990s, 2000s to the early 2010s. The rebranded network schedule also included reruns of past MTV original series such as the 2011 Beavis and Butt-head revival and . The network's relaunch took place at 6:00 a.m. ET with a rebroadcast of MTV's first hour on the air, which was also simulcast on MTV and online via Facebook live streaming, branded as "MTV Hour One". Several VH1 Classic programs were retained in the existing schedule, albeit in late night hours. Three days leading up to January 1, 2017, MTV Classic aired 24-hour block "Decade-a-thons" consisting of music videos from the 1980s leading up to the 2010s. Afterwards, MTV Classic unveiled a new automated all-music video schedule, with all of the older MTV and VH1 Classic series content removed. Since then, the only deviation from the automation has been "roadblock" simulcasts of the annual MTV Video Music Awards and MTV Movie & TV Awards to remove any competition from fellow ViacomCBS networks, as well occasional marathons of older MTV shows to promote new series or season launches. As of the end of 2016, the channel was the least-watched English-language channel on all of U.S. subscription providers, averaging only 30–35,000 viewers on an average night in primetime, which was likely a factor in the network quickly abandoning their new format after five months. As of the end of May 2017, its numbers have slipped even further to an average of 14,000 viewers per night, only ahead of the moribund Esquire Network and beIN Sports, which at that time of the year is in its non-prime sports season. Even those low numbers were halved by the end of July 2017, as that month's ratings showed it averaging 7,000 viewers per night, ahead of only the beIN networks. If not for the addition of the seven Entertainment Studios Networks to Nielsen monitoring at the end of 2017, along with a decline in beIN Sports's ratings, it would have been the lowest rated English-language network in 2017 with a 14,000 viewer/night average. Since then, it has steadily remained the fourth-to-last ranked network, behind beIN Sports and ESN's Comedy.TV and its five-network cumulative "ESN Lifestyles" entry for the remainder of its networks. As of June 2020, MTV Classic's ratings are no longer reported by Nielsen.
