It's hardly a secret that Email (the killer-app of the 90's) and SMS (the killer app of the 00's) has reduced the need for standard postal services such as letters and postcards (the killer-apps before the late 90's).

But now, a Swiss initiative is trying to take advantage of the synergy between the digital and physical communication technologies rather than viewing them as separate entities.

The Swiss post office, Swisscom mobile and the museum for communication has introduced the world's first MMS self-service stamp. Users are encouraged to MMS their own pictures to a website where people can vote for their favorites by SMS. The 4 most popular motifs will be produced as genuine stamps.

The motto of the initiative is 'Swiss mobil - Ein Land unterwegs' / 'Swiss Mobile - A Country on the Go'.
