Not a definitive answer, but interesting references:

First appeared in England in 1820

General Electric developed a system in 1953 that they called Smell-O-Rama. They demonstrated its potential by exhibiting a three-dimensional image of a rose accompanied by floral scents.[5]

I would guess that “-o-rama” and “-o-matic” come from diorama and automatic, respectively, whilst “-o-vision” comes from television, but that the ‘e’ was changed to an ‘o’ under the influence of “-o-rama”, “-o-matic”, and the Grecian -o- infix. † Raifʻhār Doremítzwr 21:33, 5 June 2007 (UTC)

Inspired by lollapalootza? which dates from a late 19th/early 20th century American idiomatic phrase meaning "an extraordinary or unusual thing, person, or event; an exceptional example or instance.
The word has also caused a slang suffix to appear in event-planning circles as well as in news and opinion shows that is used synonymously with other suffixes like "a-go-go", "o-rama", etc. The suffix "(a)palooza" is often used to imply (often in hyperbolic language) that an entire event or crowd was made over that term, e.g.: "Parks"-apalooza, "Gaff"-apalooza, etc."
