Short answers, pulled from the story.
Peter Green named the band by combining the surnames of drummer Mick Fleetwood and bassist John McVie. Green chose the name strategically to entice McVie, who initially declined to join, preferring the steady income of his existing work with John Mayall's Bluesbreakers.
Fleetwood Mac have sold more than 120 million records worldwide, making them one of the world's best-selling musical acts. Their album Rumours alone had sold 40 million copies worldwide by 2003 and over 19 million in the United States, earning a diamond certification from the RIAA.
Rumours won the Grammy Award for Album of the Year in 1978. The album was released in February 1977 and generated four top-ten singles, including Stevie Nicks' US number-one "Dreams" and Lindsey Buckingham's "Go Your Own Way".
Buckingham and Nicks joined Fleetwood Mac on New Year's Eve 1974. Mick Fleetwood had heard Buckingham's music while visiting Sound City Studios in Los Angeles and asked him to join; Buckingham agreed on the condition that Nicks, his music partner, be included.
After the real band temporarily disbanded in late 1973, manager Clifford Davis assembled a different lineup and sent them on a US tour under the name "The New Fleetwood Mac", starting on the 16th of January 1974 at the Syria Mosque in Pittsburgh. When audiences discovered the real band was not performing, the tour collapsed amid hostility and bottle-throwing, leading to a lawsuit that was settled out of court years later.
Fleetwood Mac were inducted into the Rock and Roll Hall of Fame in 1998. Members inducted included the 1968-1970 lineup of Mick Fleetwood, John McVie, Peter Green, Jeremy Spencer, and Danny Kirwan, as well as Rumours-era members Christine McVie, Stevie Nicks, and Lindsey Buckingham. The band also received the Brit Award for Outstanding Contribution to Music the same year.
