FOSTER CITY, Calif.--()--Conviva, the intelligence cloud for streaming media, released streaming and social engagement data for Round 1 of the March Madness men’s NCAA basketball tournament today, analyzing Facebook, Twitter and Instagram accounts for the 64 participating teams as well as streaming numbers related to game viewing. Overall, the 2021 March Madness tournament is the most streamed in history with the first round setting a record of more than a billion minutes streamed across 32 games in just two days.

Streaming viewing on televisions for Round 1 increased significantly to 68% share of time spent streaming, up from 48% share in 2019 and just 41% share in the opening days of 2018. Unsurprisingly, Roku captured 40% share of streaming devices for big screens; Amazon Fire TV came in second place with 26% share of viewing time, followed by Samsung TV with 10% and Apple TV with 8% share.

On the social side, engagements per March Madness social post rose an average of 164% for teams in Round 1 as compared to the regular season. Oral Roberts saw 15X growth of engagements per social post versus the regular season, followed by VCU which also netted quadruple-digit gains. Overall, teams tallied three million total cross-platform engagements over just two days, with Wisconsin, Syracuse and Illinois taking the top three spots for total cross-platform engagements.

“From the Super Bowl to the World Series, streaming and social video has become a cornerstone of every major sporting event as more and more fans use these avenues to follow the sports they love,” said Nick Cicero, VP Strategy, Conviva. “As streaming quality continues to improve and fans find new ways to engage with each other and their favorite teams, we expect the winning partnership between streaming and sports to continue.”

Data for this report was collected utilizing Conviva’s newest solution, Viewer Insights, which enables marketers and content creators to build and engage audiences with the right mix of social media, advertising, and streaming content.
