On this day in 1993, the New Yorker magazine published a cartoon by Peter Steiner. A large dark dog sits at a desk in front of a computer; a smaller white dog sits on the floor beside him; the large dog says to the small one “On the Internet, nobody knows you’re a dog”.
On 14 November 2010, the Joy of Tech blog published a cartoon by Nitrozac and Snaggy. It’s very similar to Steiner’s; but, this time, the large dog is saying to the small one “It used to be that on the Internet, nobody knew you were a dog. Now, on a social network, everybody knows you’re a bitch“.
On 12 June 2013, the Joy of Tech blog published another cartoon by Nitrozac and Snaggy. It has two panels. The left panel, headed “In the 1990’s”, is a colourized version of Steiner’s original. The right panel, headed “Now”, shows two NSA agents in a control room. One says “Our metadata analysis indicates that he is definitely a brown lab”. The other says “He lives with a white and black spotted beagle-mix, and I suspect they are humping”.
