A new report published by Tsinghua University is pointing to another decline in ad sale revenues among China's newspapers.

The analysis shows newspapers in China have seen a 15 percent decline in ad revenues through the whole of last year.

This would represent the 4th year in a row of declining revenues.

Media industry revenues overall in China surpassed one-trillion yuan last year for the first time.

The report says this is mostly due to the expansion of Internet-based media services.

Ad revenues through the Internet have now surpassed that of Television in China.
