SAN FRANCISCO — The TV Everywhere system for allowing online viewers to watch channels from the US’ patchwork of cable operators is booming thanks to sports popularity.

“We saw about a 250% increase in TV Everywhere streams this past quarter over the previous year,” says Adobe’s Primetime VP Jeremy Helfand.

“Live sports has been a catalyst. That type of content has been an inflection point for how consumers should be experiencing television. Sports content grew six-fold this past quarter over the previous year.”

Helfand’s numbers come from Adobe’s US Digital Video Benchmark, which measures TV Everywhere consumption, for 21 2014.

We spoke with him at a the TV of Tomorrow conference.  Disclaimer:  Adobe Primetime sponsored our coverage of the event.
