Silicon Valley is a place that is located in the southwest edge of the San Francisco Bay area in California. It is the place where the original semiconductor chip making industry was located. With silicon as there raw material, a newspaper writer gave the place its name, "Silicon Valley", but it wasn't always called Silicon Valley. Before the name was given, in 1956 the area was originally called "Valley of Heart's Delight". For 41 years now, the name "Silicon Valley" is still sticking. Silicon Valley is an important place because it is the place where electronics are developed such as mobile phones, medical equipment, and other electronics used in everyday life. It is also home to many major companies such as Apple, San Disk, Facebook, Google, Ebay, and Twitter. You could say that the place is pretty popular. It is the place where there is power. So remember the name Silicon Valley.
