While looking around for a little about the 8-pin DIP
package, I
checked into the 555, as it was introduced about the same time as the
8-pin DIP appeared. This site (albeit a 2nd-source, not direct ref)
says the 555 in 8-pin DIP was introduced in 1971 (page 2):

But what I was surprised about was the statement about the 555 still
selling a billion units in 2003. I thought it had faded from
popularity since the '70/'80's as I can't recall seeing one in a new
product in many years. Apparently I'm not looking hard enough. Where
are all these 555's going?
who knows? But they sure must sell alot of embeded cpu's for all the usb
crap out today.
