Mediacom reported that it lost 5,000 basic video subscribers during the first quarter of 2012, while it gained 21,000 high-speed Internet and 9,000 telephone customers during the period.

Its basic video subscriber losses improved compared to the fourth quarter, when it lost 16,000 subscribers. But the Middletown, N.Y.-based cable MSO counts 63,000 fewer video customers than it did this time last year.

The average Mediacom video customer spent $124.23 monthly during the first quarter, up from $109.17 during the same period last year. Mediacom saw its video revenue drop 4.1 percent, to $118.1 million, in the first quarter, while revenue from its cable modem business jumped 11.3 percent, to $55.4 million, and phone revenue increased 1.4 percent, to $16.5 million.

Like other cable MSOs, Mediacom is driving increased revenue from selling high-speed Internet, phone and transport services to businesses. Its revenue from business services increased 30.7 percent during the first quarter, to $19.4 million, and ad revenue increased 6.3 percent, to $11.9 million.

Earlier this week, Consumer Reports ranked Mediacom last on its list of the top triple-play providers.

In March, the MSO announced new customer service initiatives, including a move to offer subscribers 30-minute arrival windows and a 90-day money back program. It will be interesting to see how those customer service initiatives impact its subscriber growth during the second quarter.

Mediacom saw its total Q1 revenue increase 2.6 percent, to $221.2 million. Operating income rose 5 percent, to $83.4 million.
