The surprise ending to HBO’s The Jinx: The Life and Deaths of Robert Durst set off the kind of online buzz (not to mention law-enforcement attention) most documentary makers could only dream off, inspiring 35,000 tweets seen by 2.8 million people, Nielsen said in its weekly Twitter TV ratings.

That was good enough to put the show’s sixth and final episode in the week’s Top 10 for series and specials, and drew posts from Twitter notables such as Jimmy Fallon, Anderson Cooper and Josh Groban among others:

For all the high-profile attention The Jinx earned however, it still couldn’t get past another documentary series, the latest from ESPN’s 30 for 30 sports docs, which ended up fourth in the Twitter TV ratings.

The ESPN doc, called I Hate Christian Laettner, debuted after the NCAA announced the brackets for this year’s college basketball national tournament. It describes the seemingly undying enmity that Laettner, a center at Duke University, earned for sinking one of the NCAA Tournament’s most famous shots, as time ran out in overtime to defeat Kentucky and send Duke to the 1992 Final Four. Given the 87,000 tweets the doc set off, people appear to still have a strong opinion about Laettner.

Three stalwarts – The Bachelor, The Walking Dead and fast-rising newcomer Empire – topped the series and specials list, and The Voice, per usual, put both its episodes of the week into the top 10.

On the sports side, three of the conference championship games that would help set this year’s NCAA brackets made it into to the Top 10, including the games for the Big 10, SEC and ACC. Wisconsin and Kentucky sewed up two of the four No. 1 seeds in the brackets as Kentucky continued its unbeaten season and quest to be the first undefeated national champion since 1976.

Two of worldwide soccer’s biggest sideshows – England’s FA Cup match between Manchester United and Arsenal and Europe’s UEFA Champions Cup match between Chelsea and Paris St. Germain – also made the top 10. The sports Top 10 was otherwise filled out by NBA games in the stretch run to the playoffs, led by a faceoff between aging defending champ San Antonio and the team headed by LeBron James, Cleveland.

As always, Nielsen adds a series of caveats to its numbers, to wit:

Nielsen Social captures relevant Tweets from three hours before through three hours after broadcast, local time.  Unique Audience measures the audience of relevant Tweets ascribed to a program from when the Tweets are sent until the end of the broadcast day at 5am. Sports Events include those on Broadcast and National Cable Networks only across all day parts. For multicast events, networks are listed alphabetically and metrics reflect the highest Unique Audience across all airing networks.
