Netflix remains the streaming giant, but they've got competition

While Netflix remains the giant in the world of over-the-top (OTT) streaming, other services are staking their own claims to the landscape.

According to a new report by comScore, more than half of America's wi-fi connected homes have at least one OTT streaming service (streaming services that don't require an additional cable subscription). The dominant service, in a whopping 75 percent of those homes, is Netflix—presumably because no one wanted to miss out on Stranger Things.

Other services include YouTube, in 53 percent of those homes, and Amazon, in 33 percent of those homes. In a bit of a surprise, Hulu was being streamed in only 17 percent of those homes. HBO Go was only in about 5 percent of homes, but given how many people share those passwords, maybe that shouldn't come as a shock (even if it is a federal crime).

Another surprise: the appearance of Sling TV, Dish Network's cordless streaming service, on the list. While it lags Netflix in terms of subscribers, the live aspect seems to be pushing it higher in terms of engagement. It surpassed Netflix in that category, garnering an average of 47 viewing hours a month compared to Netflix's 28.

Quick caveat, though: SlingTV's offerings include plenty of live sports channels, including the entire ESPN lineup, multiple Fox Sports channels, NBC Sports, regional sports networks and single-sport channels like NFL Network, which is a huge factor to take into consideration when looking at engagement numbers.

And now that there are more of those cordless services being offered—including PlayStation Vue, DirecTVNow, and YouTube TV—we can expect to see more of those options creeping up. Overall, comScore reports that 11 OTT services reach one million or more homes every month.

As for the 25 percent of homes that don't subscribe to Netflix, YouTube and video game streaming service Twitch are the big leaders. And while Netflix is the big leader by device (Roku, Xbox, etc), it's third place in FireTV homes, behind Amazon (natch) and YouTube.
