It would be nice to think that any intelligent life that is within 100 light years and sufficient receiving technology could have been watching our satellite broadcasts, but I fear not.It was mentioned in the film Contact, that the power of the Berlin Olympic transmissions using relatively low frequency VHF were of a magnitude that may have been picked up elsewhere without too much difficulty.The use of satellite uplinks since the mid 70s does give a far more focused beam of signal, and a star system within 30 light years or so, which happens to be inline with geostionary satellites and the uplink station, could well have programme content for a fleeting microsecond as the Earth and satellite move in relation to the sky, but its unlikely they would get anything that makes them want to spend time in piecing together potential content, even if it reappeared on a daily basis. (especially if it was a shopping channel)
