Despite attempts by Mark Cuban, Comcast, Netflix and others over the years, movie studios and big theater chains have combined to keep the "release window" in place -- until now. That window is the period of time between when a movie premieres in the theaters until you can actually buy or rent it to watch at home, and since the dawn of VHS it's usually remained at about 90 days or so. Now the Wall Street Journal says Paramount is testing out a plan with AMC and Cineplex to release a couple of movies in theaters just six weeks after they premiere instead of three months.
