But some critics (批评人士)，including some Internet service providers，have warned that the Internet will collapse with millions of people downloading programs at the same time.Over the next four years，it is thought that the number of videos watched over the Internet will be four times as big as that.Broadband companies claim that the service will cause “traffic jams”，which will cost millions of pounds to get it to normal.
