In 1991, Bellcore engineer Cliff Kushler devised T9 text entry, speeding up typing on mobile phones

Before T9, texting on mobile phones was a tedious affair, requiring multiple presses per letter. In 1991, Bellcore engineer Cliff Kushler revolutionized this with T9, meaning 'Text on 9 keys'. This software used a dictionary and language rules to predict words, transforming the 12-key keypad into a faster typing tool. T9's predictive text paved the way for modern autocorrect and autocomplete features, making mobile communication significantly more practical.
