In the furor over Colorado’s “Amazon tax,” senators might have stumbled on the Holy Grail of state governments: a legal way to tax the Internet. It began Feb. 4 during a late-night hearing for the Amazon bill, formally known as House Bill 1193, The Durango Herald reports. Dozens of local partners of Amazon.com and other Web retailers arrived to protest because similar bills in other states had led to the mass firings of people like them. A Republican senator, Greg Brophy, convinced Democrats to rewrite the bill, and what emerged four days later made Amazon and tax officials across the country snap to attention.
