 As we know,it's the beginning of the end for TV. Apple has released Apple TV,a tiny white box that connects the shows and movies you've downloaded from the computer,and wirelessly (無(wú)線地) sends them to your TV screen.

  No longer will you have to pay a monthly fee to your cable (有線的) company to watch your favourite show. Apple's iTunes has made it possible to download a TV show for about $ 2,keep it stored on your computer and watch it whenever you want. It's a blow to the cable networks,which offer services that are often expensive and make hundreds of channels and thousands of shows nothing to watch.

  American networks have gone one step further,allowing audiences to watch their shows for free online. If the cable companies don't keep up with technology,we'll soon be giving them up.

  "This is the biggest kind of entertainment in history," says Colin Dixon, "I don't think that traditional broadcasts—cable and satellite—are going away tomor?row,but they must change to keep the market share."

  The Internet changes businesses at an unbelievable speed. Now it's happening with video. Canadians are being kept behind the times. Some Canadian channels are starting to follow American companies. Global offered Survivor: Cook Islands on?line,and CTV is doing the same for Degrassi：The Next Generation t And cable companies say that video on demand and personal video recording technology can compete with the Net.

  "You watch when you want it," says Michael Lee,adding that the Net doesn't give viewers the opportunity to just sit on the couch and flip (瀏覽) through chan?nels.

However,it takes time.

  "Up until this year even the US sites didn't offer a lot of online content. We've seen an explosion of it this fail," she says.
