SMS may be losing appeal after 20 years
Text messaging, which quickly gained global popularity, faces crackdowns, competition

Amid the 20th anniversary of the short messaging service (SMS) this month, analysts say the world's most popular mobile service is facing stiff competition from emerging applications for internet-enabled smartphones.

Since the first SMS text message, "Merry Christmas", was sent in Britain on December 3, 1992, the format - with a maximum of 160 characters - has quickly become one of the most popular forms of communication.
Worldwide, there are about 3.6 billion active users - 78 per cent of all mobile-phone subscribers - who send out about 10 trillion text messages a year.
In China, China Mobile statistics show that mainland users sent out 736.1 billion text messages last year, up from 502.74 billion four years ago.
However, the Shenghuo Xinbao newspaper reported late last month that China Mobile's SMS revenue had declined by 11.7 per cent year on year to 46.46 billion yuan (HK$57.23 billion) last year.
