A Washington Post review of the new Trading Spaces emphasizes the smaller spaces the show worked with:

Though it was technically impossible to indict the cable channels — especially HGTV — for their role in the quick-mortgage fantasia, the connections were plain to see: the schedule was (and still is) littered with shows that spur house envy, encouraging viewers to live in a constant state of renovation, makeover and upgrade. Homeownership became the highest expression of citizenship, while decor became the chief signifier of class. “Trading Spaces,” which premiered in 2000, helped ignite that craze, making it safe to waste entire Saturday afternoons watching home-improvement shows. Yet it hardly deserves all (or any) of the blame.

The show returns Saturday (with a long reunion special preceding it), essentially unchanged and contagiously giddy, full of its usual surprises and reveals. Looking at the first of eight new episodes, one is reminded of “Trading Space’s” conceptual purity: It never goaded anyone into ditching their old house for an open-floor-plan, granite-countertop McMansion beyond their means. Its core principles were to work with what you have, on a restrained budget. It preached a DIY ethic, asking couples to swap houses and redo a room, aided (some would say strong-armed) by a crafty professional designer and carpenter.

A few quick thoughts:

1. The scale of renovation on Trading Spaces is much more doable for the average American homeowner compared to the whole house makeovers on many other shows. How many people have the budget to do multiple rooms, particularly creating all new kitchens or master bathrooms? Or, who has the time to hand over their house for weeks as opposed to doing renovations over a weekend?
2. The rooms on Trading Spaces tend to be much more varied than the typical home shows that often emphasize an expansive kitchen and open concept first floor. The HGTV shows encourage a homogenous style, moving from stainless steel appliances and granite countertops to shiplap, white cabinets, and open shelving.  American homes tend to be unique inside, particularly in certain rooms where people to have eclectic styles and uses.
3. While the review above does not blame Trading Spaces for the larger shows to come, once you on television continue (1) glorifying the single-family home as the expression of individual tastes (a long-standing American tradition) plus (2) suggesting that people should be renovating their homes (part of the shift from living in homes to seeing homes as investments), is it a slippery slope to large-scale renovations in big houses?

On the whole, there is a lot that could be said from the move from Bob Villa to Trading Spaces to House Hunters and Property Brothers alongside shifts in American housing. Of course, it is hard to make causal arguments about how watching these shows directly changes behaviors.
