Hawaiian Telcom signed up a record 2,822 television subscribers in the second quarter as it continued to make inroads into rival Oceanic Time Warner’s commanding market share.

The state’s largest phone company, which reported a 43.3 percent drop in second-quarter earnings, said Monday it now has 23,100 subscribers for its TV service. That represents 16.3 percent of households that have been "enabled" on Oahu through the company’s fiber-optic network to receive HawTel’s programming.

HawTel, which launched the TV service July 1, 2011, enabled 12,000 households during the quarter to bring its overall total to about 142,000 homes on Oahu. Oceanic has about 90 percent of the Oahu cable TV market.

"What was a nascent business three years ago has now developed into a $23 million annualized revenue stream for us and growing," HawTel Chief Executive Officer Eric Yeaman said on an earnings conference call.

Despite the growth of its TV business, HawTel’s net income fell last quarter to $2.2 million, or 20 cents a share, from $4 million, or 36 cents a share, in the year-earlier period when there were one-time items that affected earnings. Those items included a $6.5 million gain from sale of property and a $3.7 million loss for the early retirement of debt.

Overall, revenue slipped 0.2 percent to $96.8 million from $97 million after a 5.5 percent decline in the company’s landline customers and lower equipment sales.

But revenue from HawTel’s TV service nearly doubled to $5.5 million in the quarter from $2.9 million in the year-earlier quarter after picking up about 9,500 subscribers over the past 12 months. HawTel’s TV service is now in 51 percent of the marketable households on Oahu. On June 1, HawTel launched a new advertising campaign that included a TV commercial featuring Miss Hawaii 2005.

"It’s still early-stage, and the new campaign is a supplement to the steady buildup of advertising we did throughout the first half of the year," Yeaman said. "But we are experiencing a lift in promo cost, and second-quarter performance did realize some benefit from the new campaign. So the reach and awareness of Hawaiian Telcom TV is steadily growing, giving us positive momentum and positioning us to further increase our video market share."

High-speed Internet revenue also was up as the number of subscribers increased 1.9 percent year over year to about 91,400. And the company realized $2.1 million of net incremental data center services revenue from SystemMetrics, a local data center that HawTel bought for $16 million in September.

SystemMetrics, founded in 2011, provides data center services to more than 400 small- and medium-size businesses.

HawTel’s stock closed down 62 cents at $28.02 Monday on the Nasdaq Stock Market. The earnings were released before the market opened.
