But do people even know to tune in? In past years, the lead-up to a new cycle of Runway came with an onslaught of publicity: constant on-air promos, posters and billboards every which way you turn, and print ads galore. But this time, there's been a noticeable dearth of promotion for Bravo's No. 1 show. Sure, there have been television commercials and the occasional print announcement, but the usual plastering of New York City buses and subways, for instance, has been suspiciously absent.

Some people suspect that Bravo is trying to sabotage the show before it heads to Lifetime next season -- a way of getting back at producer Harvey Weinstein for taking away their banner hit. A source at Bravo called that theory "ridiculous," and added, "Why wouldn't we want Runway to do well on our network?"

Lifetime announced today that it has picked up the hit Bravo series Project Runway and will begin airing the series' sixth cycle, which debuts in November. In a statement, The Weinstein Co., which produces the show with executive producers Dan Cutforth and Jane Lipsitz of Magical Elves, announced that it entered a five-year deal for the show with Lifetime -- a development that prompted legal action by NBC/Universal. In the same statement, the Weinstein Co. acknowledged that NBC filed a lawsuit today in New York Supreme Court in an attempt to block the series from moving to Lifetime. "We believe that this lawsuit is without merit. While good for the market for lawyers, it is always unfortunate when parties try to win in court what they have lost in the marketplace," said David Boies, counsel to The Weinstein Co.

The NBC/Universal lawsuit asserts that the company had been negotiating with The Weinstein Co. for a year to obtain additional installments of Runway but the production company "never intended to negotiate in good faith." It goes on to say, "Instead, The Weinstein Co. threatened to take future cycles of the program to a competing TV network unless [NBC] agreed to pay many millions of additional dollars to Weinstein to acquire a 'package' that included TV rights to second-tier Weinstein films unrelated to Runway." The Weinstein Co. was contractually obligated to give the NBC-owned Bravo the right of first refusal when it got the offer from Lifetime, says the suit.

Weinstein has already begun pre-production of Runway’s fifth season for Bravo, which is scheduled to air in June.

NBC released this statement today: "NBC Universal has continuing legal rights related to Project Runway, including a right of first refusal to future cycles of the series, which The Weinstein Company unfortunately has refused to honor. NBC Universal regrettably had no alternative but to bring legal action to enforce its rights to this program, including the right to decide whether it is in the best interest of the company to continue to air the show under the proposed financial terms."
