Same with me. My parents showed me TOS even before I could think. So the TOS Crew was sort of a second family - on screen. But one of my oldest conscious memory of Star Trek was watching TNG in the living room with the family. We went so far as to record every episode and watched it for dinner, like a celebration.
But though I'm of the TN-Generation, TOS was a constant escort. All the gaps between the two generations/time frames (esp. in relation to our own time frame) were an important item to consider for my analysis.
