Microsoft Corp.'s Bing search engine also reviewed the most popular social media services in its year-end list released Monday. (Tumblr ranked sixth behind Facebook, Pinterest, Twitter, LinkedIn and Instagram.)
Tumblr's look back delves into some of that well-worn territory, too, though its selections may send some people scurrying to a search engine to find out more. For instance, the most blogged-about actor on Tumblr during this year was Benedict Cumberbatch, an English performer who has primarily had supporting roles in U.S. films (he most recently played the villain Khan in "Star Trek Into Darkness.")
Cumberbatch doesn't appear in a separate year-end roundup to be released Tuesday by Yahoo, but "Star Trek Into Darkness" tops Yahoo's rankings of the most-searched movies on its site.
Tumblr's list also underscores its audience's devotion to the British TV series, "Doctor Who." The top actress rankings include three performers — Billie Piper, Karen Gillan and Jenna-Louise Coleman — who have appeared on "Doctor Who," a show that didn't make the cut on Yahoo's list of the most popular TV series.
In a tip to Tumblr, Yahoo is highlighting three of the blogging site's categories in its own breakdown.
Now Yahoo Inc. wants 6-year-old Tumblr to start selling more ads. One of the upcoming categories in Tumblr's retrospective will highlight the best ads that appeared on the service this year.
