Hulu provides a nice faceted approach for browsing clips and episodes.
1. Filtering navigation in left sidebar
2. All facets exposed; "Clip" selected under Type facet
3. "Comedy" selected under genre facet; Selecting "show more" expands to show other choices under facet
4. "NBC" selected under Source facet
