Today, almost every household in America has a colored television. Nielsen Holdings estimates that 96.1 percent of U.S. citizens have access to television. -

Microprocessors are important because they allow computers to be included in everyday items such as cell phones, traffic lights, ATM's, etc. The Intel 4004 had a clock speed of 740 kHz with 2250 transistors. The new AMD Zen 3 (2020) has a clock speed of 3.4-4.9 GHz with 4.15 billion transistors -
