message in php doesnt show new lines

[Pouncer]

            $query = "SELECT `Announcement` FROM `announcement`";
            $result = mysql_query($query) or die("Query error<br/>" . mysql_error());
            $row = mysql_fetch_array($result);
            echo $row[0]; 

in the mysql database the message is in paragraphs, but on the php page the message just displays in 1 big lump. how can i fix it?
