In the past, the manufacturing processes for analog and digital circuits were so different that they could not be combined on the same chip on a large scale. There were big companies that made digital chips and a host of smaller companies that made analog chips. That changed about ten years ago and analog circuits are now included on SOC designs. That has caused a shift in the industry, as the large SOC manufacturers have absorbed most of the new analog circuit designers who used to go to smaller companies that specialized in analog. The smaller companies are faced with competition for designers and a shrinking niche for their specialized products.
Texas Instruments has $12B in sales and analog is a large (and growing) chunk of that.
