According to a recent American study, 11 percent of people thought the abbreviation HTML (hypertext mark-up language, used to create web pages) was a sexually transmitted disease. They were also confused about “gigabyte” (27 percent thought it was an insect found in South America), “motherboard” (42 percent said the ‘deck of a cruise ship’), “MP3” (23 percent thought Star Wars robot), and “Blu-ray” (18 percent saw a marine animal). It is unsurprising then that 77 per cent of the sample had no idea what the term “SEO” meant.
