theodp writes "Before there was Pong, there was Ping-Pong. Table tennis began in 19th-century Victorian England as a parlor game for the upper-middle class, with cigar box lids used as paddles. Today, as BusinessInsider half-joked, federal law requires all tech startups to have a functional ping pong table. Photographer Alec Soth discusses his love of the game in a NY Times interview and shares some vintage photos of the sport from his new limited-edition book Ping Pong. So, why do people — especially lots of computer programmers — get obsessed with Ping-Pong? Table tennis is 'a way to do a physical sport that has actual athletic qualities but is kind of contained,' explains Soth. 'There's a real mental element to it. It's not chess, but your brain is engaged. It's a break from neuroses.'" As workplace stress relief games go, a ping-pong table is also a lot easier to carry than an air hockey set-up or a bowling alley.
