April 19: Verizon Communications Inc. added 193,000 FiOS Internet customers in the first three months of the year to end the quarter with 5 million. The company says it will stop selling DSL Internet service in areas where FiOS is available. DSL is slightly cheaper than FiOS Internet service, but much slower.

April 24: AT&T Inc. says it added 718,000 subscribers to its U-verse high-speed Internet service in the first quarter to reach 5.9 million. The company says those gains more than offset losses from DSL. AT&T added a net 103,000 landline broadband customers after factoring in the DSL losses.

April 26: Time Warner Cable Inc. says it added 792,000 high-speed data subscribers to end with 11.1 million. Most of the gains came from the acquisition of Insight Communications, a cable TV company with customers in Indiana, Kentucky and Ohio.

May 2: Comcast Corp. says it added 439,000 Internet subscribers to end with 18.6 million. That was the best quarterly result in four years. Meanwhile other cable companies report a slowdown in the recruitment of new subscribers, since most households already have broadband. Comcast appears to be gaining subscribers from households with slower phone-company ‘‘DSL’’ broadband.
