Reality Bytes: ‘The Sing-Off’ finale airs Monday night

The world of reality TV has a few last-minute holiday presents for fans of the genre.

Here are this week’s stocking stuffers:

‘Sing-Off’ goes ‘Glee’

Who knew that “Glee” would make a cappella singing a hot commodity?

Last December, NBC debuted its a cappella singing contest “The Sing-Off” to mixed reviews. The show shined a light on the singing mode, but it was a snore.

“Glee” changed all that.

The high school musical show took off this year and it reawakened an interest in vocally powered music — complete with theatrics.

The phenomenon rubbed off on season two of “The Sing-Off” and it’s a whole new show. Yeah, I was a hater last year. Now I’ve been catching up for hours via On Demand.

This year’s “Sing-Off” attracted professional singers making comebacks, and young groups from Yale and the Berklee College of Music.

The groups amped up the fashion, stage moves and choices of music. The singers also employed hip-hop and electronica-based beatbox vocals to pump up the tunes. These acts proved that Radiohead’s “Creep” and Lady Gaga’s “Paparazzi” could be amazing a capella numbers.

It’s working, because this season’s viewership — especially for 18+ audiences — is off the hook.

Catch “The Sing-Off” finale Monday on NBC.

‘Survivor’ producer goes up against ‘Idol’

“Survivor” producer Mark Burnett has the golden touch. Now he’s going head-to-head with “American Idol.”

Last week, Burnett announced his new reality show “The Voice of America.” The singing competition debuts this spring on NBC. The network obviously loves “The Sing-Off’s” ratings.”

There will be lots of competitive twists on “The Voice of America.” The show will place singers in teams and have them work with coaches. Plus, the judges will have their backs turned from the singers when they perform?!

2011 will be the year of vocal contest wars, as this show goes up against “American Idol” and Simon Cowell’s “X Factor.”

David Arquette, reality host

David Arquette wasted no time after splitting with wife Courtney Cox.

The film star jumped into the waters of reality TV and landed a new show. Arquette just hooked up with Merv Griffin Entertainment to create and host “Ranking the Stars.”

The show will feature celebrity panelists ranking each other on a variety of topics. To take things up a notch, each episode will host celebs that have something in common.

I’m sure the Kardashians are already signed up.
