What were the first technology regulated in the US?

The first technologies regulated in the U.S. included telegraphy and railroads in the 19th century. The Federal Communications Commission (FCC) was established in 1934 to oversee telecommunications, including radio and later television. Additionally, the Interstate Commerce Commission (ICC), created in 1887, was the first federal agency to regulate economic activity, particularly in the railroad industry. These early regulations aimed to ensure fair practices and safety in rapidly evolving technologies.
