W5 takes viewers inside the modern world of weddings - a $4 billion-a-year industry in Canada, worldwide it's a $300 billion business. From wedding designers to Hollywood-style videos, themed events to spectacular locations, weddings have come a long way from a church ceremony, quick photos, and a night at the local hall. 

It consists of designers, caterers, purpose-built venues. A quarter of Canadian couples now spend between $30,000 and $75,000 on their wedding. Three per cent spend more than $100,000.

Without looking too hard, W5 has found video of weddings performed on rollercoasters, under water, on mountaintops. There have been wedding party wardrobes that cost six figures, others that cost not a dime because the couples married au naturel.
