NEW YORK (AP) — Comcast Corp.'s third-quarter net income jumped 50 percent in the third quarter, helped by a one-time tax settlement, growth in Internet subscribers and fewer defectors from its cable service. Cable providers have been consolidating as more viewers shift to watching video on mobile tablets, computers and smartphones rather than through traditional cable TV stations. [...] channels like HBO and CBS have announced standalone streaming services, signaling the industry is undergoing a sea change. Excluding a hefty one-time tax settlement, net income totaled 73 cents per share, beating analyst expectations of 71 cents per share, according to FactSet.
