This was the first US mainstream television commercial featuring a gay couple

In 1994, Ikea ran this television commercial in major East Coast US markets. (Interestingly, the commercial's art director was Patrick O'Neill who went on to be Chief Creative Officer at everyone's favorite Silicon Valley start-up disaster Theranos!)

From a 1994 article in the Los Angeles Times:

A few East Coast Ikea stores have been targeted by angry protesters who have jammed phone lines since last week. One store in Hicksville, N.Y., was briefly evacuated last week after a bomb scare. No bomb was found.

At issue is the homosexual relationship between the two men in the Ikea ad, who talk about how buying the dining room table together shows their commitment to each other. If it becomes clear to other major marketers that Ikea's business is not harmed--and perhaps even helped--by the ad, it could profoundly affect the way major advertisers speak to gays and lesbians.
