ACHIEVEMENT OF THE YEAR: Grew revenue 8.3 percent to over $4 billion in the first three quarters of 2017 and launched a Beatles Channel with Apple Corps. SiriusXM's stock price also rose almost 20 percent.
PROGRAMMING WITH THE STARS: Under Greenstein's leadership, the satcaster drew 1.6 million net new subscribers in 2017. Programming wins: recruiting LL Cool J to executive-produce SiriusXM's classic hip-hop station and Taylor Swift marking the release date of Reputation with a performance in SiriusXM's New York studio that included an emotional cover of Tom Petty's "American Girl."
POST-#METOO STRATEGY: Greenstein says he honed an approach to harassment years ago: "It's just something that has to be addressed and not hidden from. You have to be aggressive not just when these events happen but all year round."
