When was the CN Tower built?

The CN Tower in Toronto, Canada is a communications and observation tower. This building was completed in 1976, and at that time was the world’s tallest free-standing structure.

The 20th century saw an explosion in communications technology. The first radio broadcast was made almost at the beginning of the century, when Reginald A. Fessenden transmitted music and words in 1906.

By the 1920s, radio provided a major form of entertainment for many people around the world. Then, in 1926, a Scottish engineer named John Baird developed the first successful television set.
