I agree with almost all the points that Rick Clancy makes as he places his bet that Blu-ray discs will be around for far greater than five years. That said, I actually think few in the industry would disagree with that. The question I’ve been asked more often is how long will Blu-ray grow, especially compared to the decade or so of growth that DVD saw, and how deep will its penetration reach, at least in the U.S..
Compared to the near monopoly that DVD had as a format for selling movies, Blu-ray will face more competition, including stronger legacy competition in the DVD. However, barring any breakthroughs such as DECE changing the nature of downloads, Blu-ray will continue to offer a superior convenience factor for movie buying.. (As for rentals, digital distribution may make inroads there more quickly.) Therefore, I think that Blu-ray will grow for more than the next five years, and see it starting to peter out in about seven or eight years.
