Fox's Empire Series is getting a lot of attention as of late, and many are curious as to why. The network TV's fastest growing drama series did not just top the charts, but it might also get a concert series. You've read it right, a concert series.

Empire made its TV screen debut just last Jan. 7, and many are already hooked to watching the new musical series. If you haven't seen it yet and are thinking "another Glee," then there is a lot more to know about the new series from Fox.

Unlike musical the TV series Glee, Empire is not about teens or love or high school life. The new soap is about a sick hip hop star, his ex-wife, and their not so happy family. The story revolves around hip hop and entertainment company, aptly named "Empire Enterprises," which family members are all trying to get a slice of.

The series' episode last Wednesday garnered an astounding 13.9 million views, which made it the not just night's most-watched series, but also the highest-rated one in all key demographics, according to sources. This left everyone asking how big can Empire actually get?

To think that Empire has pushed American Idol to the second spot in terms of ratings, it looks like Fox executives are in for a treat. Among the 18 to 49 age demographics, it landed at a 5.4 rating-twice the rating that American Idol has received.

Fox's goal for the new series is to tap into viewers that most series do not really reach.

Empire's 18-to-49 rating in households earning more than $100,000 a year is at 2.6, which indicates a more moderate- and low-income audience than most networks usually target in their programs, according to sources.

And since the series has been getting a steady influx of viewers since it was initially aired, network bosses are looking into launching a concert series for Empire. At the moment, executives want to make the brand bigger and of course, its future.

"What we learned on Glee and what we tried to do on Glee is be very cognizant that the music business is the tail of this dog-the show is the thing. But we are certainly looking down the line. There's no reason not to think of having all sorts of ancillary opportunities with this show. We're certainly thinking about idea of doing a live concert series," Fox TV Group co-CEO and co-chair Dana Walden said.
