On March 6, 1899, the German company Bayer receives the patent for acetylsalicylic acid, which it markets as aspirin. The active ingredient, salicin, is found in tree bark and had been used as a pain reliever in European folk remedies for centuries (medical historians believe Hippocrates used it), but sparingly because it tasted bad and irritated the stomach. In 1897, Bayer developed a powder form of the substance that eliminated the side effects. It began producing the tablet form of the drug in 1915. Today aspirin is the most commonly used drug in the world. Bayer, however, lost the rights to profit from it in post WWI settlements, and did not regain it until 1994.
On March 6, 2001, the death spiral of Napster begins, as it begins to comply with a federal court order to prevent the sharing of copyrighted material. Developed by Shawn Fanning, a Northeastern University student in the summer of 1999, Napster gave users the ability to share .mp3 files with other users via the internet. At the height of its popularity in mid-2000, some 60 million users were active worldwide; the overwhelming majority of the material being shared being copyrighted music. The heavy metal band Metallica brought Napster to court when it learned that one of its songs was being shared before its release. Hip hop artist Dr. Dre soon followed with a similar complaint, and when A&M Records sued in February of 2001, the writing was on the wall. Napster would shut down just 3 months later.
