Elon Musk says a new Twitter CEO is starting in six weeks, rumors suggest NBCU's Linda Yaccarino

Tech titan Elon Musk is living proof that promises are meant to be kept - especially when they're made on Twitter. After a poll asking whether he should step down as CEO, Musk is making room for a new queen bee to rule the Twitter hive in about six weeks.

• He's keeping mum on the identity of the incoming CEO, but what we do know is she'll be calling the shots while Musk stays on the sidelines as executive chairman and chief technical officer.

Twitter's Next CEO: Word on the street (or in this case, The Wall Street Journal) is that NBCUniversal advertising bigwig Linda Yaccarino might be the mystery woman poised to take over the Twitter reins. Known for pushing the boundaries of ad effectiveness measurement, Yaccarino and Musk seem to be two peas in a pod, often seen rubbing shoulders at industry events.

• The plot thickens when you consider the ongoing partnership between NBCU and Twitter, which was recently extended to host 2024 Olympic videos. And when Yaccarino suggested via tweet that Twitter should resurrect Periscope, it got us wondering: what could this mean for Twitter's future?
