CNNMoney.com is reporting that the U.S. Justice Department approved the merger between satellite radio companies Sirius and XM Monday, more than a year after the two companies first announced their deal.

We've been waiting for the DOJ to determine whether an XM-Sirius merger was anti-competitive, or if other media companies such as Clear Channel, CBS, and even Apple served as genuine alternate options for music and media customers, according to the article.

The FCC must also approve the deal before it's finally a go. "The merger would combine the nation's only two satellite radio companies and create a company with about 14 million subscribers. It would bring together Sirius' most well-known content, including Howard Stern and National Football League games with XM's Major League Baseball as well programming from Oprah Winfrey."

The merger would impact all kinds of devices and services related to the two companies, including Sprint's SIRIUS Music and AT&T's XM Radio Mobile. Cell phone satellite radio has been on the table for three years now; the merger could finally give it a bump in popularity.
