Some of the Prime Network's affiliates were "time-share" networks, which shared channel space with other cable networks on certain cable systems, due to issues with channel capacity that would not be resolved until headend upgrades to allow additional networks to be carried on a 24-hour basis during the 1990s.
In 1993, Liberty Media, NBC and Cablevision Systems Corporation formed Prime SportsChannels America, a venture in which the companies pooled programming and advertising sales between Prime and Cablevision/NBC's regional sports network group SportsChannel.
