The cell phone, based on the idea of honeycombs, was invented by Martin Cooper. People told him that the game wasn’t worth the risk. However, they lined up at the stores on the very first day of sales! This device had a memory of 30 numbers, could work for an hour, and required a 10-hour charge.
Emojis were created in 1963 by American artist Harvey Ball. He received only $45 for his invention. A few years later, businessmen Bernard and Murray Spain started selling and licensing the yellow “smiles,” which brought them more than $50 million.
