There are plenty. They're ridiculously cheap, so they get used everywhere. Checking DigiKey for the cheapest 8 bit and 32 bit micros: Atmel's ATTiny5-MAHR is $0.196 each at qty 100 (no further price breaks listed, full reel of 3000 is non-stock/call for price). The Cypress CY8C4013SXI-400T is $0.49 each at qty 2500 (full reel). 2.5x the price is a big difference, and matters a lot when you're producing thousands or millions of something. Tons of power supplies use an 8-bit (or even 4-bit) microcontroller instead of or in addition to a dedicated switchmode controller ASIC. They're also ridiculously common as LED dimmer controllers, keypad controllers for microwave ovens, etc. 8-bit micros aren't going anywhere any time soon. Price matters too much.
