Cable is close behind due to its early lead, but the growth rate for these services is slower because of the greater diversity of cable households and services (not all service providers offer TVE).

According to ABI Research, satellite operators are further behind, due to slower starts and lack of in-house broadband services, but offer some novel experiences like Dish's Sling place-shifting technology.

The vast majority of US TV consumers already use advanced interactive features like remote programming a DVR, the firm found. But they also need further education about TVE services, particularly to help navigate content availability and fragmented device support.

"The market is still developing with many of the early growing pains, like authentication, finally starting to take a back seat to the content," commented senior analyst, Michael Inouye. "In many respects the technology is in place to increasingly offer wider reaching TVE services. Securing the rights to broader content distribution is the primary remaining hurdle, but once standard metrics are developed the content floodgates are expected to open wider."

Outside of the computer, Apple's iPad continues to be the most supported TVE device in the US market. In fact, iOS and Android smartphones and tablets capture the lion's share of device support, besting even the popular game consoles.

"In the multiscreen and OTT space the MVPDs are moving at a relatively fast pace – rapid enough that in some instances the platforms have outpaced consumer awareness," added ABI practice director Sam Rosen. "Beyond consumer education, a great deal of work remains to best optimise the user experience, one that satisfies consumers' increasing penchant for on demand content but also ensures the content is adequately monetised. This objective is creating new opportunities for a wide range of companies within the greater content value chain."
