Big Apple
"The Big Apple" was popularized as a name for New York City by John J. Fitz Gerald in a number of horse-racing articles for the "New York Morning Telegraph" in the 1920s. The earliest of these was a casual reference on 3rd May, 1921:
Thousand Oaks, California
While agriculture was the dominant industry in Thousand Oaks until the 1950s, a number of high-tech companies moved to Newbury Park in the 1960s. Today it is home to a number of high-tech and biotech companies, and has been dubbed "the next Silicon Valley" for this reason. Thousand Oaks has been named one of the wealthiest cities in the United States. It was ranked the seventh richest city in America by Trulia in 2013, while it was ranked the 13th wealthiest U.S. city by NerdWallet in 2016.
