A year before Star's launch in 1990, another fifth network attempt was made with the "
Premier Program Service", a joint venture between
MCA Inc. &
Paramount Communications, with stations owned by Paramount's
TVX Broadcast Group & MCA's WWOR-TV as charter outlets. The network was set to launch in 1991. It was in early 1990 that MCA & Paramount approached certain Fox stations with PPS affiliate deals. However, when Fox objected to the solicitations, PPS was scrapped. After Star's shutdown, yet another attempt at a viable fifth television network would be made in 1993, when the
Warner Bros. Domestic Television Distribution subsidiary of
Time Warner would partner with the
BHC Communications subsidiary of
Chris-Craft Industries to launch the
Prime Time Entertainment Network (PTEN). However, both Warner Bros. & Chris-Craft would abandon PTEN in late 1993 to focus on launching their own respective joint venture TV networks. PTEN network would eventually cease operations in 1995. It would also be in that year that two new viable fifth television networks would be launch by both of PTEN's parent companies: Warner Bros. would partner with the
Tribune Broadcasting subsidiary of the
Tribune Company to launch
The WB Television Network, and, the
United Television subsidiary of Chris-Craft would partner with the
Paramount Television subsidiary of
Viacom to launch the
United Paramount Network (UPN). After launch, both The WB and UPN would compete with
Fox. Both The WB and UPN would eventually be replaced in 2006 by
The CW, another viable fifth major television network joint venture between
CBS Corporation (successor to the original Viacom & eventual full owner of UPN) & Warner Bros. Meanwhile, with the launch of The CW in 2006,
News Corporation, then the parent company of Fox, would take its stations formerly affiliated with UPN & use them to launch in 2006 what then was the newest sixth television network,
MyNetworkTV. However, by 2009, amidst poor ratings and viewership, MyNetworkTV would be switched from a TV network to broadcast TV syndication service. ==Programming==
