try 'echo *.html', it will do the same thing, since you're doing shell globbing, which isn't a feature of ls at all. shell globbing will fail if there are too many files in the directory, and shell globbing can't filter in reverse like that. grep works for an arbitrary amount of data and can filter in reverse.

Code:
# See all files ending in .html
ls | grep "\.html$"
# see all files not ending in .html
ls | grep -v "\.html$"

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
