Need to spice up your life?

What's that? A Spice Girls reunion you say!? You may be rolling your eyes now while remembering the 1990's girl-group phenomenon, but I know in 1996 you were dancing around in your fluffy slippers and pink pj's to their breakout hit "Wannabe".

There has been talk for a Spice Girls reunion for a year or two now, with debate on whether or not a reunion tour would be profitable at all. However, past reunion tours would suggest it would be.

For example, the NKOTBSB reunion tour earned sizable profits, grossing over $40 million with 51 shows last year. Likewise, if the past is any indicator of the future, the smaller 2007/2008 Spice Girls reunion tour grossed a reported $70 million, suggesting that a larger, more publicized tour would do quite well.

Ray Waddell, Billboard Magazine employee, says that at least two decades is the ideal time to wait when beginning to market nostalgia.

"When seeking to tap into nostalgia for teens, 20 years gives those original fans time to grow up [and] get married...plus there is hopefully a little more discretionary income available," Waddell told to eonline.

However, while this idea makes sense, I feel like the girls' 2007-2008 mini-reunion could have hurt their rumored upcoming tour. While, according to Waddell, the 20-year-mark is ideal, I would think the fans who attended the last show would be less inclined to purchase tickets for a new one. Although this problem is probably only minor and could be solved by different tour cities and venues.

One thing I know, if a tour is announced, I'll be in line for tickets.
