The current century -- spanning the years from 2001 to 2100 -- is referred to as the 21st century. This inspired many forward-looking 20th century events, company, and product names, like the Century 21 Exposition (another name for the 1962 Seattle World's Fair), Century 21 Real Estate, and Century 21 Television (producers of Sylvia and Gerry Anderson Supermarionation shows like Thunderbirds and Captain Scarlet).
