Here is one attempt at typesetting "emphasized quotes" within a document.

\documentclass{article}
\usepackage[margin=1in]{geometry}% http://ctan.org/pkg/geometry
\usepackage{xcolor}% http://ctan.org/pkg/xcolor
\usepackage{lipsum}% http://ctan.org/pkg/lipsum
\usepackage{multicol}% http://ctan.org/pkg/multicol
\newcommand{\myquote}[2][black!10]{%
\medskip
{\setlength{\fboxsep}{.1\columnwidth}%
\noindent\colorbox{#1}{\begin{minipage}{\dimexpr\columnwidth-2\fboxsep}
\raggedright\sffamily\bfseries\Huge#2
\end{minipage}}} \par
\medskip
}
\begin{document}
\begin{multicols}{3}
\lipsum[1]
\myquote{``This is a very important quote''}
\lipsum[2-5]
\myquote[orange!30]{``\ldots and here is another.''}
\lipsum[6-9]
\end{multicols}
\end{document}
Since you reference newspaper or magazine as the source, multicol provides an easy-to-use columnar presentation. geometry was used to increase the page footprint (setting the text block margins to 1in), while lipsum provided some dummy text.
The idea behind \myquote[<color>]{<text>} is to typeset the quote using a bunch of predefined font selections: \raggedright\sffamily\bfseries\Huge, all of which is mean to make them stand out from the regular text in terms of font size, type, family and alignment. The default background colour is 10% black (black!10, provided by xcolor), but you can change this to suit your document colours.
Of course, other "magic" can also be added to the formatting as defaults that are modifiable, if needed.
