Something like this should work (*UNTESTED*):

#!/usr/bin/perl
use strict;
use warnings;
use File::Find;

my @directories = qw(/var/www/html /var/www/html2 /etc); #if you don't 
know all the directories and are okay with the script running for a 
while you could just specify /
my $line = quotemeta("Copyright 2010"); # Or whatever your line actually 
is . . .
my $copyright_file = quotemeta("copyright.htm");
find(\&wanted, @directories);

sub wanted {
     if($_ =~ $copyright_file) {
         open(my $fh, '<', $File::Find::dir.'/'.$copyright_file) or die 
"Couldn't create read handle: $!\n";
         my $new_file = undef;
         while(<$fh>) {
             if($_ =~ /^$line$/) {
                 $_ =~ s/2010/2011/;
             }
             $new_file .= $_."\n";
         }
         close($fh);
         open($fh, '>', $File::Find::dir.'/'.$copyright_file) or die 
"Couldn't create write handle: $!\n";
         print $fh $new_file;
         close($fh);
     }
}
