A variety of fan-organized and media campaigns kept "Friday Night Lights" on the air when NBC wanted to cancel the show.

Fans pulled together through Facebook groups, online petitions and e-mail campaigns to show NBC that they supported "Friday Night Lights." In the spirit of "Roswell" and "Jericho," fans searched for a symbol that they could send to the network to show their support, so they sent light bulbs and eyedrops to NBC.

Light bulbs are pretty self-explanatory, but why eyedrops? The Clear Eyes-brand eyedrops were a reference to the team's motto on the show: "Clear eyes, full hearts, can't lose." The VH1 show "Best Week Ever" organized the light bulb campaign, while the eyedrops were a totally fan-driven gimmick.

Despite the show's low ratings, these fan-supported efforts kept "Friday Night Lights" on the air for five seasons before NBC announced its cancellation in 2010.
