Ok, I am posting this in response to an email that I got.

Friends,
I want to be able to watch Conference on
TV in the future so I felt this was a good cause.
This is important. Please, if you don’t wish to
participate, return this to the person who sent it to
you so they can at least keep this going, or forward
it to someone you think will wish to participate.

Dr. Dobson is going on CNBC to urge every Christian to
get involved. I hope you will think about signing this
and forwarding it to all your family and friends.

Dr. James Dobson, with Focus on the Family, pleads for
our action. An organization has been granted a Federal
Hearing on the same
subject by the Federal Communications Commission (FCC)
in Washington, DC.

Their petition, Number 2493, would ultimately pave the
way to stop the reading of the gospel of our Lord and
Savior, on the air waves of America. They got 287,000
signatures to back their stand! If this attempt is
successful, all Sunday worship services being
broadcast on the radio or by television will be
stopped. This group is also campaigning to remove all
Christmas programs and Christmas Carols from public
schools! You as a Christian can help! We are praying
for at least 1 million signatures. This would defeat
their effort and show that there are many Christians
alive, well and concerned about our country. As
Christians, we must unite on this. Please don’t take
this lightly. We ignored one lady once and lost prayer
in our schools and in offices across the nation.
Please stand up for your religious freedom and let
your voice be heard. Together we can make a
difference in our country while creating an
opportunity for the lost to know the Lord.

This is a bogus email. I went to Snopes and checked it out because I specific part seemed odd.

Please help defeat this organization and keep the
right of our
freedom of religion. When you get to 1000 please
e-mail back to:

Email petitions have no power, James Dobson would have real petitions. Anytime you get an email that seems overly grand or has this revolutionary information, please run it through Snopes(or a similar site) before you email it to everyone.
According to Snopes this myth has been around since 1975. There was an original petition Number 2493 and this is what Snopes said,

The intent of the infamous RM-2493 was to ensure channels reserved for educational purposes ended up being used for education and not be taken up by religious groups looking to use them for a different purpose. RM-2493 has since come to be understood as a petition seeking the ban of religious broadcasting, and from there it was further attributed as the work of Madalyn Murray O’Hair, arguably the best-known atheist of our times. How this great a misunderstanding of the actual petition then in front of the FCC came about is anyone’s guess.

The real petition the FCC was asked to consider was filed in December 1974 and defeated in August 1975. Even through the smokescreen of thousands of people misunderstanding what it had been asked to consider and heatedly arguing issues that weren’t on the table, the FCC saw its role in such matters quite clearly:
As a government agency, the Commission is enjoined by the First Amendment to observe a stance of neutrality toward religion, acting neither to promote nor inhibit religion.

Added note to the original sender, I have seen this one before so you are not the first;).
