Apple TV in 1998
"Introduced in Febrary 1997, the PowerMac 6500 ..... was the first computer, Mac or PC to break the 300 MHz barrier."
I had one, with an Apple-made TV tuner that slotted into a video capture slot.
I now have an iMac with a USB TV tuner, which is my living room TV and looks very nice. It's digital, so it requires a credit-card size smart card in order to work. I cannot imagine Apple building such a reader into an iMac, when USB devices are so readily available.
