Communication has evolved significantly over time from early human expression through paintings, to the development of writing systems like Egyptian hieroglyphs, to the creation of the Greek and Latin alphabets still used today. A major breakthrough was Gutenberg's 15th century invention of the printing press, which made books and reading more widely accessible beyond just the clergy. The industrial and digital revolutions of the 19th and 20th centuries brought many new communication technologies like radio, telephone, television, and the internet which have continued to advance into the 21st century with fewer borders and limitations.
