How has the American agriculture changed during this last century?

How has new technology (smart phones, social media,) changed the way American farmers operate?

• How has new technology (including smart phones, social media, Web 2.0, etc) changed the way American farmers operate? How will this technology impact agriculture in the future?

• Answer:

  I think what you mean to ask is: What is the impact of web technology on American farming", rather than the more general "new technology". Web technology has made access to information much easier than before. Before, farmers would have to depend on their fellow farmers from neighbouring farms or government or private support agencies for support and help. Now, with web, farmers can search for answers themselves and even make contact with people from farms, agencies, and organizations across the world to help on information or to solve a particular problem. I think even Yahoo Answers is one good example where questions gets asked and answered.
