1. A Brief History of Cell Phones
Cell phones have come a long way since their inception in the 1970s. The first mobile phones were bulky and offered limited functionality, primarily making voice calls. The Motorola DynaTAC 8000X, released in 1983, is widely recognized as the first commercially available mobile phone. It weighed nearly 2.5 pounds and was priced at $3,995.
