HBO added over 5 million domestic digital subscribers across its HBO and Cinemax services in 2017 — it's largest annual increase ever, the company announced in an SEC filing Thursday.

Why it matters: The increase is a result of a years-long overhaul of the company's content distribution strategy to broaden their subscription base so that they don't need to charge cable and satellite companies more to carry their content.
