I tend to believe so. As a kid I used to watch a lot of variety, from old sitcoms like I Love Lucy to the newest thing Nickelodean had to offer. I enjoy a lot of sitcoms that aired during the 1970s, and that was before I was even born. Looney Tunes and Tom & Jerry occupied me for a while, and I did like The Flintstones and The Jetsons.
The only reason why I feel that the 2000s haven't had too much to offer is because much of the programming lacks a variety. It has all the latest shows with an overabundance of reality TV shows, and while some channels are dedicated to older stuff, they aren't airing everything from times past. I can still recall many cartoon shows and live action shows I saw when I was little that haven't aired for a good 10 or so years on TV. However, I guess that's starting to become a little to no issue, since we can watch these shows in their entirety on DVD anyway.
