• The streaming search engine Reelgood provided Business Insider with data on the 20 most popular series on HBO Max among Reelgood's 2 million users in the US.
• Of the top 20 shows, 12 can be found on Max but not traditional HBO.
• Three months after launch, HBO Max still isn't on the Roku and Amazon Fire TV platforms, the two biggest streaming distributors. That means subscribers can only watch HBO content on these devices, not Max originals or exclusives.
• The popularity of Max content with Reelgood users suggests this could be hampering the service.

Three months after launch, HBO Max still isn't on the Roku and Amazon Fire TV platforms, the two biggest streaming distributors.

That means that HBO Max subscribers can't watch Max originals or exclusives on these platforms, and new viewing data suggests this could be hampering the service.

The streaming search engine Reelgood provided Business Insider with the top 20 HBO Max shows that its 2 million users in the US had streamed from May 28 to August 16, based on data from the number of streams initiated via Reelgood on desktop and mobile devices. Reelgood did not disclose the demographics of its user base, which could not be a representative sampling of HBO Max users. But still, the data gives a snapshot into what HBO Max users are watching.

While HBO originals like "Game of Thrones" and "Watchmen" are popular, Max exclusives and originals have also broken through. Of the top 20 shows on HBO Max, 12 can be found on Max but not traditional HBO. In July, WarnerMedia also released its own (unranked) list of top 25 shows HBO Max shows, which included eight Max originals.

This all means that viewers using Roku and Amazon devices to stream are likely missing out on a big chunk of HBO Max's popular programming. That includes hit shows that WarnerMedia dropped millions of dollars for exclusive streaming rights to, like "Friends" and "South Park," along with originals like DC's "Doom Patrol" and "Legendary."

WarnerMedia's parent company AT&T announced last month that 4.1 million users had activated the Max app, 3 million of which signed up directly to Max. That means that just over 1 million users who were already paying for HBO through a cable or live TV provider accessed Max, a small number compared to HBO's more than 30 million subscribers. The lack of Roku and Amazon support could be one reason more have not switched.

Below are the top 20 shows on HBO Max, according to Reelgood data:
