Facebook, Twitter, Instagram and other forms of social media have transformed how we communicate. From personal relationships to professional interactions, social media has had a dramatic impact on virtually every facet of society, including the law. A new book, "Social Media in a Nutshell," written by University of Dayton School of Law Professor Thaddeus Hoffmeister and University of Texas Social Media Law Professor Ryan Garcia, shows the wide-ranging influence social media has on criminal investigations, jury selection and other aspects of our legal system. 

One of the most popular Instagram accounts belongs to National Geographic, with submissions from the best nature and wildlife photographers on the planet. 

New technology meets America’s pastime in sports photographer Brad Mangin’s new book: Instant Baseball: The Baseball Instagrams of Brad Mangin. As he tells Mark Heyne, he spent the entire 2012 baseball season, from spring training through the World Series, photographing the game and the players with Instagram on his iPhone4s, not his usual Canon cameras.
