After decades of providing Pay-Per-View movies to the industry, iN DEMAND has decided that on May 31, 2016 we will cease delivery of our three linear Pay-Per-View movie channels (iN4, iN5, iN6). Our decision to close down these three channels was driven by the evolution and proliferation of VOD movie content and the continued industry-wide decline of the Pay-Per-View movie business.

Their PPV event channels will stay. BTW, some smaller systems don't even have VOD, so their subscribers may have to wait for new movies to pop up on HBO/Showtime/Starz.
