Social media in action can be observed on the example of fives from the top of construction companies in America - these are Edge Homes, Innovative Construction, Dream Finders Homes, C -Dm Network and Patriot Contractors. These construction organizations increase their turnover of profit every year, while their sites are full of links to many social networks, including Twitter, Facebook, Googole+ and Pinterest.

For example, Innovative Construction on their pages on social networks receive up to 5,000 like daily. This demonstrates that the material is interesting to the general public, and not just representatives of the construction industry and those who “want to understand”.  And the organization Patriot Contractors uses the social buttons "I like" and "share" on unique and standing materials and due to this are the spread of their materials on the network.
