does some one know if silver spoons airs in the us

I don't think it's airing anywhere in the U.S. right now. The user, SBTB Geek got the station KDOC to take Silver Spoons into consideration, though. There's a number where you can directly talk to the man in charge of this station and tell him how much you want to see Silver Spoons. The number is:

John Atkinson
(949) 442-9800 (long distance, ughh!) ext. 119
Mon- Fri 8:30 a.m.- 5:30 pm (Pacific time)

The shows they are taking into consideration are: ALF, Small Wonder, Mr. Belvedere, Facts Of Life and Silver Spoons
