I can't see the Blockbuster analogy fully working here. It seems that a big reason why the old video rental model died was simply convenience. .com is the more convenient choice due to inertia. It seems to me that a better analogy is that the new TLDs seem more like suburbs to a city. .com still lies at the city core, but the suburbs provide for a new type of Internet resident -- those who are willing to trade convenience and location for price and value. Like Detroit, or the rust-belt in the 80's it's possible that the core becomes rotten, but it seems in those cases, the nexus still remains, but becomes depreciated. It will be interesting to see how domain real-estate follows the patterns exhibited in real-estate as the new TLDs become more ubiquitous; will there eventually be a revival of .com similar to the urban revivals we've seen? Or maybe that's just stretching the analogy a bit too far :)
