BEIJING, Oct. 9 (Xinhua) -- China's internet service and related sectors continued to see fast expansion, with double-digit growth in both revenue and profit in the first eight months, official data showed.

The sectors' total revenue amounted to 752.2 billion yuan (about 106.4 billion U.S. dollars) during the January-August period, up 20.9 percent year on year, according to the Ministry of Industry and Information Technology (MIIT).

Business profit came in at 70.9 billion yuan, surging 32.7 percent from the same period last year.
