Censorship and the issue of media freedom in Russia have been main themes since the era of the telegraph. Radio was a major new technology in the 1920s, when the Communists had recently come to power. Soviet authorities realized that the "ham" operator was highly individualistic and encouraged private initiative– too much so for the totalitarian regime. Criminal penalties were imposed but the working solution was to avoid broadcasting over the air. Instead radio programs were transmitted by copper wire, using a hub and spoke system, to loudspeakers in approved listening stations, such as the "Red" corner of a factory. Due to the enormous size of the country Russia today leads in the number of TV broadcast stations and repeaters. There were few channels in the Soviet time, but in the past two decades many new state-run and private-owned radio stations and TV channels appeared.
The liberalisation of Bangladesh's telecommunications sector began with small steps in 1989 with the issuance of a licence to a private operator for the provision of inter alia cellular mobile services to compete with Bangladesh Telegraph and Telephone Board (BTTB), the previous monopoly provider of telecommunications services within Bangladesh. Significant changes in the number of fixed and mobile services deployed in Bangladesh occurred in the late 1990s and the number of services in operation have subsequently grown exponentially in the past five years.

The 2006 Hengchun earthquakes occurred on December 26 at 20:26 and 20:34 local time off the southwest coast of Taiwan in the Luzon Strait, which connects the South China Sea with the Philippine Sea. The International Seismological Centre measured the shocks at 7.0 and 6.9 on the moment magnitude scale. The earthquakes not only caused casualties and building damage, but several submarine communications cables were cut, disrupting telecommunication services in various parts of Asia. Coincidentally, the earthquake occurred on the second anniversary of the 2004 Indian Ocean earthquake that devastated the coastal communities across Southeast and South Asia and 3rd anniversary of the 2003 earthquake that affected the southern Iranian city of Bam.
