Netflix dominate peak Internet traffic periods as its respective subscribers streamed 58% more titles (2.6 million) from January to September this year, than the collective number of movie disc rentals (1.1 million), according to The NPD Group.

Brick-and-mortar rental spending declined 13.2% in the first nine months of the year, to $766.8 million, according to DEG: The Digital Entertainment Group. By-mail disc rental was off 19.8% in the first nine months of the year, to an estimated $780.7 million.

NPD said the peak disc rental period in home entertainment occurred in 2007 with more than 2.5 million transactions — which is less than what Netflix streamed this year in nine months.
