Media Relations |


 |
Media have always been an important element in the cycle of shaping public opinion. They decide which topics are on the agenda or not and who is given broadcasting time or publishing space. By featuring certain points of view and neglecting others media have the ability to influence public opinion and thus also political decision-making to a significant extent.
Therefore, besides educational and publishing programs, media are an essential element in the dissemination strategy of think tanks. To spread their respective ideology they provide print media with masses of op-ed's and their top staff regularly appears on television and radio shows as political advisers or policy experts.

Satellites
Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure.
On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from fiber optic cables, so point-to-multipoint transmission increasingly becomes the ruling satellite technology. Point-to-multipoint transmission enables the quick implementation of private networks consisting of very small aperture terminals (VSAT). Such networks are independent and make mobile access possible.
In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
For more information about satellites, see How Satellites Work ( http://octopus.gma.org/surfing/satellites) and the Tech Museum's satellite site (http://www.thetech.org/hyper/satellite).
