After months of speculation, USA has officially canceled veteran sci-fi dramas The Dead Zone and The 4400, according to The Hollywood Reporter.

Although things didn't look good for the two series because they are older and expensive to make, during the past several months the cable network looked for ways to bring them back. But it ultimately opted to end their run.

"We wish we could keep all our great shows alive forever," said Jeff Wachtel, exec vp original programming at USA. "But we feel we need to give some of our new shows a platform to grow, and it's with great sadness that we say goodbye to two shows that had a great run and helped create the resurgence of original programming on our network and on all of cable."

The Dead Zone, which ran for six seasons, and The 4400, which was on for four, had aired as a sci-fi-themed block Sunday night.
