ITA Software does not market a consumer oriented flight search site.
That's probably not completely true. Matrix, although not a booking site, is one of the better flight search sites, allows consumers to find the cheapest time to leave and come back in a given month for a particular number of days of travel.
Although it's a bit of a reach to say that they "market" matrix/matrix2... It isn't terribly nice to use, they don't actively promote it, and they don't allocate it very much processing power.
That being said, I have always gotten the impression that they maintain it as a sort of testbed -- a huge number of Flyertalkers use matrix for very esoteric queries, and I'd imagine the feedback that ITA gets from those users is invaluable.
Not only will they leave it, this is the most important part for Google. I expect that they will spin it into a 'Google Travel' product and take over the travel market pronto
