So far Fox has shunned HDTV, instead using the wide-screen Enhanced Definition digital format, which the company says is perceived to be as sharp as HDTV by most viewers.
The network offers two-thirds of its nonsports programming with this system. Beginning this month, Fox will also offer wide-screen Enhanced Definition presentations of football and NASCAR racing each weekend to its digital viewers.
There is no guarantee that the broadcast networks will be able to get their HDTV offerings in front of cable subscribers' eyes, as the cable companies could decide to provide HDTV programming provided mainly by their industry. HBO and Showtime offer HDTV programming on separate channels available to DirecTV and Dish Network subscribers.
