Seven fat years, seven len years

Which industry was said to experience a "seven fat years, seven lean years" model -- seven years of boom, followed by seven years of bust.

Following that pattern, the late 60's/early 70's were great (the "-tronics" boom -- this is when Intel was funded by Arthur Rock), the mid-70's were terrible, 1978-1985 was great (the PC!), '86-92 was terrible, '93-99 was fantastic, and '00-06 was not so good.
