The majority (58%) of broadband households in the US use at least one over-the-top (OTT) video service on a monthly basis.
The research, from Parks Associates, also found that more than 25% of households use two or more services.
"Despite impressive penetration, growth of US OTT services has slowed recently, indicating the overall market for SVOD service might be saturated," said Glenn Hower, research analyst at Parks Associates.
Parks research also found that Netflix continues to dominate the OTT space, with 43% of US broadband households subscribing to its service. But after Hulu and Amazon, with 19% and 17% respectively, penetration of OTT services drops drastically.
"However, with new niche services emerging that focus on targeted content and audiences, there is still room for growth in the space," added Hower.
