Test patterns were originally printed on cards. A television camera was pointed at one, and they used that for calibration and alignment of the cameras, televisions and other equipment. Now cameras and televisions are much better and require less adjustment, and test patterns are digital and are generated by test signal generators, but test signals are still used so that people can adjust their equipment to perform optimally.

The use of test patterns as programs ended in the late 1980s or early 1990s. As television technology advanced, broadcasting stations adopted more sophisticated methods to conclude programming, such as displaying station logos or running promotional content. Test patterns were phased out as they were no longer necessary for technical calibration.
In Australia, television ceased using test patterns at the end of broadcasts in the early 2000s. The transition occurred as networks began offering 24-hour programming, which eliminated the need for test patterns that signaled the end of daily transmission. By this time, most channels adopted continuous broadcasting, providing viewers with programming at all hours.

Monsoons originate from large seasonal shifts in wind patterns caused by temperature differences between land and ocean. In the summer, warmer land surfaces lead to low-pressure areas that draw moist air from over the oceans, bringing heavy rainfall. In the winter, cooler land surfaces create high-pressure areas that reverse the wind patterns.
