When the dust had settled, the tournament amassed an average viewership of 593,090, and more than 71,200,00 hours had been spent watching the event.

Mobile Legends: Bang Bang! is an extremely popular MOBA title in Southeast Asia, one that is remarkably similar to League of Legends. Outside of the region, the game isn’t all that well-known, but Southeast Asia offers one of the fastest-growing regions for esports viewership, so it comes as no surprise that one of its localised tournaments broke records.

Between August and October, one of the most watched events esports in 2021 took place – the MPL Indonesia League. This tournament, played out on the Mobile Legends: Bang Bang! platform boasted a $300k prize pool and huge viewership figures. It beat out the PGL Major Stockholm by a considerable margin, securing 76,940,000 hours of watch time. However, the record-breaking CSGO tournament did have the edge in peak viewership.

Although the tournament was on the air for just 125 hours in total, it amassed 107,230,000 hours watched in total.

That’s a remarkable enough figure in itself, but the best tournament in Dota 2 also pulled in a peak viewership of 2,740,000. In terms of overall watch time, there’s only one tournament in esports that managed to beat The International 10.
