With so many "Reality" shows in today's time (both nationally & abroad) it's very important to understand why and how a reality show clicks. There have been so many mega-successful shows in US/UK and their counterparts in India (and so many flops) that it is necessary to learn what works and what doesn't. In this post we try to analyze deeply as to what are the different elements of a reality show and what should be taken care of while creating a new reality show.Almost all of the reality shows in India or elsewhere are localized versions of already popular US or UK shows. Here are some of the shows which have worked (in India) and some which haven't. We'll then analyze all the aspects to understand what it takes to make a successful Reality Show:Mega-successful shows-??? Kaun Banega Crorepati (Who wants to be a millionaire)- KBC 6 seems to be breaking records months before the show goes on air. The registration lines, which opened on 28th may, got 425,000 registrations against 179,000 last year.??? Indian Idol (American Idol)??? Dance India Dance (So you think you can dance)??? Bigg Boss (Big Brother)??? Successful Shows-??? Fear Factor India (Fear Factor)??? Jhalak Dikhla ja (Dancing with the stars)??? Sa Re Ga Ma Pa??? Boogie Woogie??? Masterchef India (Masterchef US/Australia)Flops-??? Zor Ka Jhatka (Wipeout)??? India's Minute to Win it (Minute to Win it)??? Survivor IndiaContestants: No doubt contestants are single biggest asset of a reality show. Wrong selection of contestants can make or break the entire show. Contestants can be broadly categorized as- "Common man" and "Celebrities". Depending upon the format of show creative team may decide to have common man or celebrities or a mix of both as contestants. For pure talent based shows like KBC, Dance India Dance, Indian Idol etc it's imperative to have common people as main contestants otherwise it looks too dramatic and unreal (remember how we feel when a celebrity wins 50 lacs in a KBC episode?). Celebrities as contestants work very well for reality shows in which drama quotient needs to be high. Questions have been raised about such reality shows being truly "real" but now audience have kind of understood that reality shows involve either good "editing" or good "drama" to look exciting on TV. Some such shows are Bigg Boss, Survivor India, Zor Ka Jhatka. Example of shows having combination of both "common man" and "celebrities" as contestants include Fear Factor (India) and Jhalak Dikhlaja.Host: Even though host is 3rd most important thing it indeed plays an important part in taking the show to next level i.e. from success to mega-success (like Amitabh in case of KBC), Khatron Ke Khiladi (with Akshay Kumar as host) or from utter failure to moderate success (Dus Ka Dum could have bombed badly if Salman wasn't there). But in case a show lacks above 2 important characteristics chances of it failing increases- SRK could never save Zor Ka Jhatka and even KBC with SRK couldn't attract audience as much as Big B. My tip: Get a host with good sense of humour or with lot of character- Raghu/Rajiv and Rannvijay are known for their tough/macho characters and they don't need Akshay Kumar.
