How do travel sites "get" airline fares?

How do travel booking sites (travelocity, expedia, itasoftware) get the database of airline fares?

Do they purchase a service from someone that provides them with a stream of fares and updates or do they go scrape screens?

I had assumed they purchased a feed from someplace but then I saw "The O'Hare Affair", a programming puzzle on ITA Software's web page and it seems like they scrape screens.

Ideas?

I believe most of them use Amadeus

Trust me, ITA isn't scraping screens to get their data.
