In 2015, documentary photographer Carol Highsmith received a letter from Getty Images accusing her of copyright infringement for featuring one of her own photographs on her own website. It demanded payment of $120. This was how Highsmith came to learn that stock photo agencies Getty and Alamy had been sending similar threat letters and charging fees to users of her images, which she had donated to the Library of Congress for use by the general public at no charge. In 2016, Highsmith has filed a $1 billion copyright infringement suit against both Alamy and Getty stating “gross misuse” of 18,755 of her photographs. “The defendants [Getty Images] have apparently misappropriated Ms. Highsmith’s generous gift to the American people,” the complaint reads. “[They] are not only unlawfully charging licensing fees … but are falsely and fraudulently holding themselves out as the exclusive copyright owner.” According to the lawsuit, Getty and Alamy, on their websites, have been selling licenses for thousands of Highsmith’s photographs, many without her name attached to them and stamped with “false watermarks.” (more: http://hyperallergic.com/314079/photographer-files-1-billion-suit-against-getty-for-licensing-her-public-domain-images/)

The history of New York City's transportation system. New York City is distinguished from other U.S. cities for its low personal automobile ownership and its significant use of public transportation. New York is the only city in the United States where over half of all households do not own a car (Manhattan's non-ownership is even higher, around 75%; nationally, the rate is 8%). New York City has, by far, the highest rate of public transportation use of any American city. New York City also has the longest mean travel time for commuters (39 minutes) among major U.S. cities. The Second Industrial Revolution fundamentally changed the city – the port infrastructure grew at such a rapid pace after the 1825 completion of the Erie Canal that New York became the most important connection between all of Europe and the interior of the United States. Elevated trains and subterranean transportation ('El trains' and 'subways') were introduced between 1867 and 1904. Private automobiles brought an additional change for the city by around 1930, notably the 1927 Holland Tunnel.
