TiVo reported double-digit growth on its topline and better-than-expected earnings over its second quarter, driven by a jump in subscriptions. The DVR service earned 8 cents a share over its quarter ended July, a penny over estimates. Revenue climbed nearly 12% to just under $112 million. Total TiVo subscriptions surged 33% year over year to end the quarter at $4.8 million. Revenue through agreements with satellite and cable television service providers (MSOs) also increased, up 37% from a year ago. The company also said it has extended its agreement with Comcast to enable easy installation of TiVo services to subscribers.
