Victoria’s Secret has figured out how to turn lingerie into a $6 billion business.

A huge reason for the company’s success is its very successful marketing strategy. It’s known for being the beacon of all things sexy.

But sexiness was depicted differently when Victoria’s Secret was born in 1977 when it was founded by Roy Raymond.

Here’s how the brand has changed — in photos.

Then: Victoria's Secret actually resembled a boudoir.

'Raymond imagined a Victorian boudoir, replete with dark wood, oriental rugs, and silk drapery. He chose the name 'Victoria' to evoke the propriety and respectability associated with the Victorian era; outwardly refined, Victoria's 'secrets' were hidden beneath. In 1977, with $80,000 of savings and loans from family, Raymond and his wife leased a space in a small shopping mall in Palo Alto, Calif., and Victoria's Secret was born,' Naomi Barr wrote on Slate.

Now: Hints of its past are occasionally present in its Facebook photos.

Then: You would have been able to find this sort of image in a Victoria's Secret ad.

The overtly provocative nature of Raymond's Victoria's Secret was slightly altered when Les Wexner took the helm of the brand -- but make no mistake, lingerie still abounded.

Now: The company's hugely athleisure business, VS Sport, is probably as covered up at it gets.

Then: Victoria's Secret definitely relied on its Angels -- even if the ads were a little cheesy.

Now: Victoria's Secret works on balancing total sexiness with being relatable. In fact, this photo appears to be less Photoshopped than other recent photos.

Moreover, the company is very particular with who it chooses to cast as Angels; they need to not be threatening to women.

Then: Don't forget the quintessential bathrobe.

Now: Victoria's Secret is constantly looking for new ways to provoke.

Then: A full-on body suit and a sexy position was all the brand needed.

Now: This photo actually came under fire for being too sexy. People said it catered to men, rather than women -- the group that actually purchases the apparel at Victoria's Secret.

Then: The iconic Angels promoted the company's nearly as iconic sales.

Then: The bras offered full coverage.

Now: The company is famous for its T-shirt bra, but the retailer frequently shows off lacier undergarments in its imagery. Still, not every photo shows a nearly-naked woman.

Then: The company's catalogue was critical.

Now: The models are occasionally covered up -- but note the bare leg in this image. There's usually a level of flirtatiousness in the photos.

Then: Victoria's Secret has always walked a fine line of sexiness -- sure, it titillates men, but it still has to get women to purchase lingerie.

Now: Though the brand is occasionally subject to criticism for its narrow portrayal of sexiness and beauty, sales are still soaring. According to IBIS World, it holds a whopping 61.8% of the market.
