I'd written about both Comcast and Time Warner Cable's experiements with day-and-date video-on-demand in previous posts, so it was interesting to see a recent article with some more data from Time Warner. Executive Vice President and CFO John Martin said that their trials show that DVD sales aren't hurt and the VoD take-rates are significantly increased. Martin says that VoD buy rates were up more than 50 percent, while DVD sell-through increased 10 percent.
