The collaborative online encyclopedia created and maintained by a community of volunteer editors, Wikipedia is one of the most-visited websites on the internet. The nonprofit funded primarily through donations has 6.2 million articles in English—and also features articles in 250 languages, altogether attracting 1.7 billion unique visitors monthly. Pages, particularly in English, get updated with remarkable speed to include deaths, sports results, and political events.

66 years ago today, Berry Gordy founded what would become Motown Records, a Black-owned label that achieved crossover success and played an important role in the racial integration of popular music. In the 1960s, Motown ruled the airways with a style of soul music that had a mainstream pop appeal. It became the most successful soul music label, with a net worth of $61 million in 1960s dollars. In its first 10 years, Motown tallied 79 top-ten records on the Billboard Hot 100—by artists such as the Supremes with Diana Ross, the Four Tops, the Jackson 5, Stevie Wonder, Marvin Gaye, the Marvelettes, and the Miracles.
