HBO, including the HBO Max streaming service, now reaches 73.8 million global subscribers as of the end of 2021, according to news shared by parent company AT&T today ahead of the company’s fourth-quarter earnings planned for later this month. The figure tops the company’s forecast for its year-end total, which it had earlier said would be in the range of 70 million to 73 million.

It also represents a 4.4 million gain in subscribers in Q4, up from the 69.4 million reported in the prior quarter — the latter which had then represented a 12.5 million year-over-year increase. While the service was growing, HBO’s U.S. subscribers had dropped in the third quarter — but the loss had been offset by international subscriber additions. One of the contributing factors to that domestic decline had been the company’s decision to remove HBO Max from Amazon’s Prime Channels in the quarter, leading to a 1.8 million drop in U.S. subscribers (from 47 million in Q2 down to 45.2 million in Q3).
