Some Copyright Practices Are More Stupid Than Others

I just tried to check out some of the new TV programs for next fall, but some of the short clips, such as the superhero "No Ordinary Family".  I could not as it won't play in Canada.  While it may make sense to restrict programs that one has licensed to a Canadian company, it makes no sense to prohibit exposing foreign publics to the snippets being used to sell the show.  More exposure, I believe, is more exposure.  Oh well, I guess they don't want their show to do well elsewhere.
