Silicon tuner adoption in TVs and other electronics will help drive down costs, which is a pressure needed for manufactures to stay cost competitive. Electronics have to continually get cheaper for more people to buy them, unless any major breakthrough is achieved to justify high prices. This is something I will be paying close attention to.

During 1980's the TV signals received with Yagi antennas.A low noise combined with good varicaps with highly stable tuning voltage with good AFC/AGC circuits were required. Nowa days the specifications required are not so tight as the signals are strong and almost from cable and dish. A lot of architectures are possible and many designs will evolve in future.
