747 seats didn't lay flat at the time but, to your basic point, the real market for the Concorde--such as it was--was the international lawyer who had to jet over to London for the day. And it was relatively cramped compared to first class on a 747 and certainly compared to today's wide bodies. I'm not sure how much the Internet has to do with it as the Concorde never really did have a market but probably the "need" for 4 hour trips to New York or London have declined in any case.
