I've only watched a few of these shows. But in one show Georgie is watching Charles in Charge and in another Sheldon discovers Star Trek (TOS) as a brand new thing. They also are proud of the fact that they get all three network stations.
Now on TBBT Sheldon is roughly 30 years old and on YS he's about 10. So by rights the show should take place in the year 2000.
