Our Twitter Week in Review chart uses data collected and parsed for Ad Age by the What the Trend (WTT) unit of HootSuite, the social-media management dashboard with more than three million users. (Last week's chart is right over here.) We're back today with Volume 14. Scroll down below the infographic for some context -- and watch for a fresh edition of our Twitter Week in Review each Friday.
- References to celebrity deaths ruled the top trends chart again this week. Writer and filmmaker Nora Ephron's death on June 26 first showed up Twitter while she was still alive, the result of a prematurely-posted memorial essay by Liz Smith. Also garnering some posthumous Twitter love was Michael Jackson, whose fans observed the third anniversary of this death this week.
- There's no shortage of fans of Fox's resurrected animated hit "Family Guy," but the fact that it trended this week has more to do with its creator, Seth MacFarlane, whose new movie "Ted" -- starring Mark Wahlberg and a debauched teddy bear -- hits theaters today.
- The Spice Girls -- those crazy-haired, platform-shoed Britons who epitomize mid-'90s pop music -- haven't made headlines since they reunited for a world tour in 2007. But this week, all five members of the former girl group gathered to announce they'd be working together on a new musical called "Viva Forever," written by "Absolutely Fabulous" comedienne Jennifer Saunders and featuring many old Spice Girls hits.
- Nope, that 's not media mogul Arianna Huffington getting name checked in the No. 10 trend this week (the single "n" should have been a clue). Instead it's Nickelodeon's "Victorious" star Ariana Grande, who turned 19 this week.
