Time machine trivia answers

It's been 24 hours since I posted the answers to my time machine trivia test.  Click on this link if you missed the questions; now, here are the answers:

1. YES.  The first known pizza recipes were created in Italy around the 17th century.  The first pizzeria in U.S., Lombardi's, opened in New York City in 1910.  The popularity of the pie spread after World War II when American soldiers, sailors, and airmen fell in love for it.
2. NO.  Television was still experimental in the 1930s, commercial networks didn't launch in America until after World War II, and I Love Lucy itself didn't debut until 1951.
3. NO.  Although souped-up cars used to transport moonshine past pursuing police officers were commonly used in the 1930s - and organized races around bull rings may well have taken place in the '30s and were certainly known by 1941 - the National Association for Stock Car Auto Racing was not organized until 1947.  Its "Strictly Stock" division, now the Sprint Cup Series, debuted on June 19, 1949, in Charlotte, NC.  Jim Roper was the first race winner.
4. YES.  John Loud patented the first ballpoint pen in 1888.  However, the first truly popular model, Bic, did not reach the U.S. market until 1946.
5. NO.  Milton Bradley did not introduce the game until 1966.
6. YES.  "Flappers," young, headstrong, short-haired women, were popularized in the 1920s, and all products mentioned were available at that time.
7. YES.  A&W, the most common ingredient in root beer floats, was introduced in 1919.  (And if Brenda wanted to fill those floats with something else, Coca-Cola [1886] and Pepsi [1897] were also available.)
