When did Plan B become famous?

The term "Plan B" became widely used in the early 1980s as an emergency contraceptive method, initially known as the "morning-after pill." It refers to the use of hormonal medication within a certain timeframe after unprotected sex or contraceptive failure to prevent pregnancy. The awareness and popularity of Plan B increased in the late 1990s and early 2000s, largely driven by improved manufacturing processes, increased availability over the counter in some countries, and growing advocacy for reproductive rights.
