Hehe, yeah, your comment felt a bit ambiguous. > They might be reasonably different markets now, but they should not be in the future. I think that's what made me think you thought it needed to be a one-company solution. Manufacturers of vacuum cleaners and computers are not in the same market, in the sense that is relevant here, even though both plug into a wall socket. A market is not defined by a common interface, but by whether or not you compete for the same customers. A flight search service is as much a substitute for a mobile phone price comparison service as a vacuum cleaner is for a computer, therefore, those products are not in competition, therefore, they are not in the same market, they are merely technically in some ways similar products with partially overlapping interfaces.
