when was the first bag cell phone invented
Motorola Bag Phone Motorola introduced the Bag Phone line in 1990.[1] These phones offered more durability and higher power output (up to 3 watts) than more conventional cell phones of the time, such as Motorola's own DynaTAC and MicroTAC handheld phones, making them popular for truckers, boaters, and people in rural areas. Because of their durability, many examples of these phones are still in working order today.
Tea bag The first modern tea bags in the Western World were hand-sewn fabric bags; tea bag patents date as early as 1903.[4] First appearing commercially around 1904, tea bags were successfully marketed about 1908 by the tea and coffee importer Thomas Sullivan from New York, who shipped his silk tea bags around the world.[5] The loose tea was intended to be removed from the bags by customers, but they found it easier to brew the tea with the tea still enclosed in the porous bags.[6] The first tea bag packing machine was invented 1929 by Adolf Rambold for the German company Teekanne.
