Excerpt from The Top Five Campaigns to Save TV Shows from Cancellation on greatwhitesnark.com:

What did fans send?

Sunflower seeds, a favorite of 4400 character Dr. Burkhoff (played by fan-favorite character actor Jeffrey Combs). Combs has also apparently "supported" the campaign, whatever that means.

Yeah, I support the ongoing existence of my job, too, buddy.

How successful was the campaign?

Not very, unfortunately, in spite of impressive turnout.

Individual fans had sent about 30 pounds of sunflower seeds to the USA Networks offices by January 30 of this year. Following that, North Dakota company Giants Snacks shipped nearly 6,000 bags (about 650 pounds) of seeds, with orders from about 30 states and a dozen countries. Meanwhile, over 16,000 signatures have been added to an online petition.

However, USA Network spokeswoman Kristin Schulman told the Associated Press that it would be 'very difficult logistically to bring the show back." That’s a fancy way of saying "a snowball's chance in Hell."
