Comcast soars the most in five years after profit tops estimates

Comcast rallied the most in more than five years after its focus on improving internet service paid off in the third quarter, with the largest U.S. cable provider posting a big increase in broadband subscribers. The company added 363,000 internet subscribers in the period, a 70 percent increase from a year earlier. Comcast has had only one previous quarter in the past six with larger broadband customer gains.
