"Commoditized" is probably a better word than "eliminated", but the point is that a large percentage of people who used to do something one way now do it another. For example:
Independent bookstores. Catalog retailers. Much of general retail. Antique & collectible shops. Classified ads. Yellow pages. Newspapers & magazines. Books. The music cartel. Travel agents. Realtors and education are probably next.
And yes, all (or most) of the profit that used to go to those industries now goes to Amazon/EBay/Craigslist/Google/Apple/Kayak etc.
