The first digital video recorders started popping up in American households in 1999. Now, about 20 million people have DVRs.
On Tuesday, AT&T unveiled a new DVR that expands the machine's capabilities.
AT&T's new DVR works anywhere in the home from one location and can record four shows at once. It also has another feature in which one can pause a recorded show and start watching it again in another room.
As many as seven TVs can be connected to one unit. Prices for the new DVR range from $40 to $160 per month, which includes Internet service.
