Spanish-language broadcasting titan Univision Communications on Tuesday reported a 101 percent surge in second-quarter profit as the company received a boost from its acquisition last year of Hispanic Broadcasting as well as continued ratings gains and advertising growth at its television and radio operations.

The Los Angeles-based company posted a profit of $83.7 million, or 24 cents a share, compared with a year-earlier profit of $41.6 million, of 16 cents a share. Revenue advanced 55 percent to $495.3 million.

At the company’s television operation-which includes broadcast networks Univision and TeleFutura as well as cable network Galavision and 55 TV stations-revenue rose 21 percent to $349.7 million, while operating income rose 23 percent to $134.4 million. The gains came as Univision’s stations and networks continued to rack up gains in audience, recording among adults 18 to 49 a 9 percent increase in prime time and 13 percent in total day.
