Charter Communications logged its fourth consecutive quarterly revenue decline as internet and video subscribers continued to drop. Second-quarter revenue edged down by 1.7% to $13.53 billion, roughly in line with analyst estimates.

The company posted a profit of $1.29 billion, or $10.66 a share, beating expectations of $9.98 a share. Rising competition from fixed wireless and fiber connection services has been eating into the company's home-internet subscriber base, while cord-cutting weighs on its cable business.

During the quarter, internet subscriber losses deepened, falling by 172,000 to a total of 29.4 million. Video customers dropped by 21,000 to about 12.5 million.
