The internet seizure occurred during a planned hiatus, to make room for the cast and crew's other commitments. NBC never had any intention, whatsoever, of cancelling the show mid-season. The ratings have been solid throughout the entire season, ranging from just under 5 million to almost 8 million viewers. When I said "it is one of the most popular shows on television," however, I wasn't referring to statistics. Community is one of the most popular shows on television among people with taste; I exclude the Jersey Shore demographic from my observations, just as I excuse the opinions of weasels and vampire bats.
As for not owning TV and not having access to shows, I haven't watched a televised program for at least five years. My aerial is not plugged in. Even if you don't have cable, or a TV, there is still Community. For people who are capable of opening boxes of cereal without observing the instructional "open here" diagrams, non-weasels, non-vampire bats, and people who own either a computer or a television: there really is no excuse.
