In last week's chart tallying the top TV shows on entertainment check-in service GetGlue, Olympic events dominated the chart. This week, social TV's apex predator swims to the top. Scroll down below the graphic for more notes and context.
- Shark Week, the annual Discovery Channel promotion and programming stunt, which attracted 26 million total viewers in 2011, kicked off Sunday night to its usual fanfare. But this year it's extra special -- it's the 25th year the Discovery Channel has devoted a week of programming to the ocean's toothiest apex predator. Shark Week's opening presentation of "Air Jaws Apocalypse," in which fimmaker Jeff Kurr explored the great whites off Seal Island in South Africa, beat the Olympics' closing ceremony for check-ins -- even though it attracted just 900,000 viewers, compared to the closing ceremony's 31 million. The takeaway: people really love talking about Shark Week in social media.
- Outside of the opening ceremony, Olympic events occupied three other spots on the check-ins chart this week. Most notably, the men's 4x100-meter relay event Saturday showcased the Jamaican track-and-field team's dominance -- it took home the gold, adding to Usain Bolt's medal spoils.
- After weeks of strong performances on the check-ins chart, it's time to acknowledge ABC Family's "Pretty Little Liars," which amid all the Olympic coverge and other summer TV events has managed to draw a remarkable number of check-ins in the middle of its third season. The soapy teen series is also a ratings winner among women and teen girls; it's now the No. 1 Tuesday cable series among females 12-34, and the No. 1 scripted cable series in women 18-49, according to Nielsen data.
