What year did tube lose to SS

Thanks for the answers.
The only point that I want to clarify is the use of "lost." As was posted I meant in terms of number built and then purchased by the consumers for good or bad reasons. Simply the numbers. Recall my analogy to CDs and Vinyl Records. Thus there was a time when you walked into a stereo and T.V. shop or even the predecessor to "Hi End" dealerships a brick and mortor "Stereo Salon." By then I didn't see anything tubed. I recall Macs but only as SS in the fancy stereo shops. I am unclearif they kept producing anything but the MC275 continuously. 1967 saw the introduction of the MC2105 an SS amp that had an occasional sale or two.
To be clearI am a tube person. And the Tube systems I use are winners.

The digital media sentence was an example of a major industry shift.  I remember as a kid that we had Sherwood tube equipment, but by the time the mid 60s had gone by tube gear was not what most HiFi shops were offering.  Until fairly recently there were only a few brands of tube gear available (during the 70s and 80s, 90s). It was a question asking when people remembered that shift from tube to SS.  It was not a question about digital vs analog. Almost all of my current gear is tube BTW.
