EFF: Signs are NBC Triggered Block of 'American Gladiator'
The Electronic Frontier Foundation has begun investigating why Microsoft Vista Media Centers were blocked from recording two NBC Universal shows Monday night.
The group, which advocates for Internet users, said indications are that NBC sent a "broadcast flag" that triggered the block. But Danny O'Brien, EFF's international outreach coordinator, said the block couldn't have occurred unless hardware and software makers honored the network's request to prevent users from recording the shows. It appears Microsoft may have obeyed NBC Universal's broadcast flag.
