Here are some fun historical facts....
The first condo in the United States dates to 1958, in Puerto Rico (a U.S. territory). Within the 50 U.S. states, 1960 (Utah). New York City didn't have any until 1965.
Canada's first condo was built in 1967, in Edmonton.
Sweden's first condo was built in 2009, although that country has/had bostadsrättslägenheter (housing cooperatives) earlier.
In Hungary they're pretty old but still still less than a century: 1924.
The U.K. really doesn't have many condos as such since commonholds, the equivalent, were introduced only in 2004.
Beverly Mai, completed in 1974, is widely considered to be Singapore's first condo development -- yes, only 45 years ago. In terms of public housing, the Singapore Improvement Trust was founded in 1927 but didn't do much. (Block 55 in Tiong Bahru, the first SIT public housing, wasn't opened until the end of 1936. And public housing back then was rented.) The HDB took over from SIT in 1960, and the HDB leasehold then emerged. But I don't think it was as long as 99 years at the beginning, and maybe somebody else knows the exact number.
Shares of company stock were issued at least as early as 1602 when the Dutch East India Company was established. There was a public stock flotation that closed in September, 1602. And stockholders were well rewarded for the first 94 years, or more than double the age of Singapore's oldest condo, with a steady stream of variable (and high) dividends. The company survived the tulip craze and a big swing in its share price, although the share price remained well above its 1602 IPO price at all times amidst that crazy ride. The company dissolved in 1800 after nearly 200 years in business. There are no more dividends, but the surviving share certificates now have increasing value as collectibles. In short, history's first stock IPO was a big total return winner.
Until recently (2006) Kongo Gumi was probably the world's oldest privately owned company. (Kongo Gumi had shareholders, but its stock was not
publicly traded.) Kongo Gumi was (and is -- more on this in a moment) in the temple building business in Japan, an excellent core business and locale since the company was in business for "only" 1,428 years. Takamatsu, a larger and more generalized construction company, acquired Kongo Gumi in 2006, and it's now a subsidiary of that larger company.
Even in Singapore, public stock trading is older than Singapore's oldest condo and just about as old as HDB. Public stock trading began on May 9, 1960, on the Malayan Stock Exchange in Kuala Lumpur. (This was pre-independence. The Singapore Stockbrokers' Association was founded even earlier, in 1930, and handled private sales of securities before the public exchange opened.) In 1961 a stock trading floor was established in Singapore, and the two floors were linked via telephone circuits to form one virtual exchange. That single virtual exchange was named the Stock Exchange of Malaysia and Singapore when Singapore became independent in 1964, and then the exchange split into two in 1973 when the currencies decoupled (albeit with cross-listing, infamously as it turned out later).
Anyway, my point here is that company shares are hardly new.
Publicly traded shares are over four centuries old, privately much older than that. It's the condo inventions -- the fanciful, wild, "bizarre" notion that it's possible to carve up a single building into walled/partitioned units (in all three dimensions) that are separately titled and private market traded -- that are much, much newer. Dare I say that condos are "exotic derivatives" in comparison?

To a mid-20th century observer, yes, I suppose they were. They're still utterly novel in places like Sweden and the United Kingdom.
Condos aren't the last word in "exotic" real estate products. For example, how about timeshares, where you add in another dimension to the product mix beyond 3D coordinates and various covenants: time?
....Study up on this stuff, basically. If shares of company stock, and stock funds, are new to you, OK, fair enough, then crack open a book -- Shiny Things has one -- and study up. You "only" have 400+ years of financial history you've missed.
