Phages were discovered 100 years ago, and since then phage research has transformed fundamental and translational biosciences. In this Timeline, Salmond and Fineran discuss a century of phage research, describing the roles of phages in ecosystems and in driving bacterial evolution and virulence, and highlight their impact as a source of novel reagents that revolutionized molecular biology and biotechnology.
