Aspirin's popularity grew over the first half of the 20th century, leading to competition between many brands and formulations. The word Aspirin was Bayer's brand name; however, its rights to the trademark were lost or sold in many countries. The name is ultimately a blend of the prefix a(cetyl) + spir Spiraea, the meadowsweet plant genus from which the acetylsalicylic acid was originally derived at Bayer + -in, the common chemical suffix.
