“Miami Vice” is currently airing in the US on Centric, a 24-hr entertainment channel created by Viacom as a partnership between BET and MTV Networks. The programming is targeted towards African-American viewers in the 25-54 demographic, set up to complement BET’s viewership demographic (typically 18-24) and to compete with TV One.
Centric is part of Viacom’s MTV Networks, and was fully launched in October 2009. Centric can be found on DirecTV Channel 330, and should also be on most major cable systems.
One word of caution: the episode listings on Centric’s website are most likely inaccurate. Their website says that the 4am Jan 1st episode was “Bought and Paid For”, but what’s actually on the air right now is “Back in the World”.
