517,000 relationships. 92,000 marriages. 1 million babies. Those impressive stats come from Karl Gregory, Match.com's UK manager and European director. “We've been responsible for all of those,” he says, understandably proud. “Isn't it incredible?”

It is incredible, and not just because of all the zeroes on those numbers. Match.com is also the most popular dating website in the world and, on top of that, it's one of the oldest. This year it's celebrating its 20^th birthday.

When Match launched in April 1995, it had only 100,000 users worldwide. Today, that number is 75 million users (registered since inception) spread across 40 countries. It all goes back to December 27, 1992 when, dissatisfied with traditional dating methods, entrepreneur Eric Klien created a 170-point questionnaire to game the system. The questionnaire covered everything from horoscopes, to music tastes, to cleanliness. He dubbed it the “Electronic Matchmaker” and uploaded it to his private internet database. Online dating was born.

In 1993 Klien sold his questionnaire and the domain name Match.com. The buyer was Gary Kremen, a Silicon Valley entrepreneur who paid $2,500 for it and launched Match as a dating service on the open internet in 1995. “Match.com will bring more love to the planet than anything since Jesus Christ,” he said during an interview.

He may have been right. Though stigma was high in the early days of online dating, 100,000 people registered with Match.com within 6 months of its launch. The next time it was sold (in 1998 to its current owner, IAC), it was for $50 million. Not bad for just a few years of growth.

Klien's original questionnaire is still part of the service, though it's evolved over the years. Now it's known as “Synapse,” the official Match.com algorithm. It evaluates both a user's stated preferences and their actions on the site, offering 6 tailored profiles for review each day. There is some debate about whether dating algorithms have any scientific credibility, but those big numbers at the top mean Match must be doing something right.

These days, Match.com's biggest user-group is aged 25-44 with its fastest growing demographic being the over-55s. There are more men than women on the site, but only slightly. Amongst men, the most common professions are engineering, finance and retail. Amongst women, it's secretaries, teachers and doctors. All sexualities are represented, as are all kinds of relationships. There are people looking for flings, for friendships, and for life-long partners. All these users do a lot of communicating, they send out over 415 million emails a year on Match.com.

Marriages that begin online are 25% more likely to last than marriages that begin in more traditional ways, said a University of Chicago study, so here's to 20 more years of magic from Match.com. To find out more about this service, please read our review of Match.com

While Tinder is looking for ways to increase its revenue stream with new premium service Tinder Plus, it is steering clear of any advertising that affects its service.

Although the company has strategically lent its brand to clever marketing campaigns - like Gillette’s facial hair survey and Domino’s Pizza Valentine’s Day campaign – they have avoided advertising that would compromise the app experience for users. Namely, in-app advertising.

The Gap however, decided that Tinder was the perfect fit for its new social media-inspired ad campaign: #SpringIsWeird, which included in-app advertising on Tinder. The campaign featured fake “profiles” of the Gap logo with messages including “you’re invited to the pants party” and “we’re taking 30% off all Gap denim,” which would appear when users were swiping through potential matches on the app. The Gap also created a “micro series” on Instagram as part of the campaign.

The Gap announced their campaign to a reporter for AdWeek in a story he promoted on Twitter after it was posted. But Tinder never approved the campaign, and apparently did not know it was happening.

In a tweeted response to the AdWeek reporter, Tinder’s VP of Communications & Branding, Rosette Pambakian, responded: “@GarettSloane we will be deleting those GAP profiles. It violates our TOS. We did not approve this campaign and it is not an ad.”

Trishna Nichols, The Gap’s leader of consumer engagement and brand strategies, described the campaign to AdWeek before the fallout: “We did a little something special on Tinder. It's a guerrilla [marketing] idea where you'll see a profile with clever messaging in the spirit of love and the perfect match. It's the perfect fit for Tinder.”

Unfortunately, the campaign wasn’t a fit for Tinder, and The Gap had never received authorization to post the ads. Tinder’s terms of service state that the service is "for personal use only" and that users may not use the service or any content contained in the service for "advertising or soliciting any user to buy or sell any products or services not offered by the company."

Other companies have done guerilla marketing on the app before, such as in 2013 when USA Network was promoting their show “Suits.” Advertisers for the show posted profiles of the show’s characters on Tinder, and they were not taken down. But now that Tinder is gearing up for creating new revenue streams, it could be that they will be cracking down harder on this type of “organic” advertising.

For now, The Gap will be moving forward with the campaign via social media, releasing an episode a week of its micro series on Instagram.

IAC released its Q4 2014 financial results at the beginning of February, reporting a 9% decline in profit for the fourth quarter from last year. Though revenue growth was in double digits, it was offset by higher expenses that ultimately led to the decline in profit. On the plus side, both revenue and adjusted earnings per share for the quarter beat analysts' estimates.

Here are some of the highlights from the report:

With each new dating app that joins the crowded market comes new promises to revolutionize dating. Every app swears it solves the problems of its predecessors, but one by one they all fall short.

We're patiently (or not so) waiting for the real developers to invent the perfect app, but in the meantime, Mic has taken a stab at solving one of the 21^st century's biggest problems. They've invented a Super App – one app to rule them all.

According to Mic, if one app could solve all the worst parts of online dating, it would need to:

1. Filter out lame opening messages. The Super App would have a built in communications rater so you never have to see another one-word message again. Bristlr, a new social network for bearded men, is currently testing a similar feature. Users can rate the quality of the messages they receive and those who are consistently rated highly get a badge on their profile.
2. Block copy-pasted messages. Everyone has either received a copy-pasted message or been guilty of sending one. Either way, it's not cool. Bristlr is also trying to solve this problem, by automatically sending a notification when a message you've received has been sent verbatim to other people.
3. Prevent men from overwhelming women with unwanted advances. Who hasn't, at least once, thought “I could really use a stalker blocker?” A lot of women are turned off by online dating because they feel overwhelmed by the number of unwanted (and sometimes downright creepy) messages they receive. Tinder changed the game when it limited messaging to people who had mutually indicated interest in each other. It doesn't eliminate the issue completely, but it's certainly a step in the right direction.
4. Make sure there's something else you're judged on besides looks. Deep down, we know we're all guilty of making snap judgments based on appearance. Enter dating app Talk or Not, which lets users slowly reveal pieces of their profile photo as their conversation with someone progresses. Looks factor into the process eventually, but not before charm, intelligence, and humor.
5. Weed out the creepers trolling for sex. It's not that there's anything wrong with casual sex between consenting adults, it's just that it gets frustrating to only be approached for sex if you're looking for something more. Mic suggests “A feature that would prominently note that the user in question is looking for a relationship versus strictly hoping to score,” in order to “prevent misunderstandings early on.”
6. Send you matches directly so you don't waste hours swiping though terrible profiles. Because no one wants carpal tunnel. The Super App would take the Coffee Meets Bagel approach and send matches so you don't have to waste time searching and swiping.
7. Keep your profile hidden from people you don't want seeing it. Family, exes, co-workers – none of those people need to know what you're up to online. The League allows users to sync LinkedIn with the app so that you never have to worry about someone unwanted peeping your profile.

Let us know what you'd like to see in the perfect dating app, and for more of Mic's suggestions see the original post.

Like the ending of Dexter, everyone has strong opinions about online dating. It's divisive, to say the least. Even people who have never tried it themselves are full of advice on how online dating is done properly. It's easy to dismiss them, but even the so-called experts barely have a clue about what's going on.

The truth is, it's hard to know exactly what works – and why – when it comes to online dating. We're all looking for a formula, but that formula may not exist. Or it might be as simple as “If it's working for you, keep doing it. If it's not, stop.” It's not the most poetic thing to live by, but at least it's accurate.

Fortunately, researchers are working their hardest to come up with something better. Online dating services produce massive amounts of data, allowing researchers to study it for patterns and answers to our biggest questions.

In a new paper in Evidence-Based Medicine, Khalid S. Khan of Barts and the London School of Medicine and Sameer Chaudhry of the University of North Texas sought to develop an “evidence-based approach to online dating.” They reviewed 86 studies in search of insight into optimizing the online dating experience, and came up with a few interesting observations:

#1: Choose a screen name that begins with a letter towards the front of the alphabet. Khan and Chaudhry found that "A variety of measures of success [in the offline world] ... are correlated with names higher up in the alphabet." It's pretty simple when you think about it: "Screen names starting with a letter near the top of the alphabet are presented first" in search listings, making it easier for names beginning with later letters to "be lost in the bottom of the pile."

#2: Keep your writing simple. Your online dating profile is not the place for flowery language. "Simple language, not overcomplicated wording, is likely to result in significantly higher ratings of intelligence because people are naturally drawn to words that are easy to remember and pronounce," Khan and Chaudhry write. The easier you make it to process the info in your profile, the more likeable you are. Likeable text also creates the impression of physical attractiveness – more time spent reading your profile, particularly the headline message, increases exposure time to your primary photo and consequently increases interest in you.

#3: Aim for a 70:30 ratio of writing about yourself and writing about what you're looking for. For all but the most ardent narcissists, writing about yourself can feel awkward and uncomfortable, but it's ok to toss humility out the window a little bit. That being said, you should also spend time describing the kind of person you're hoping to meet. A profile that's only about you will attract far fewer responses than a combination of who you are and what you are looking for,” the researchers write.

Coffee Meets Bagel has been overshadowed by its more aggressive competitors (like Tinder), but lately has emerged as a serious, lasting contender in the dating app space. The company is showing its app has real growth potential by securing $7.8 million in a Series A financing round led by existing investor DCM Ventures. Quest Ventures and Azure Capital also participated in the round.

This round of financing is followed by the steadily growing success of an app whose founders like to take things slowly, testing what works in each market (starting with its launch in 2012 to New York and Boston markets) before moving on to the next. Recently, the company expanded from an iPhone-only app to include an Android app as well, opening markets further.

Coffee Meets Bagel sets itself apart by making the dating app experience feel more personal. People are connected through their social networks – through mutual friends on Facebook, for instance – so there is a level of assurance that you can avoid the scammers and fake profiles. Also, CMB users receive only one match per day, avoiding the whole Tinder hook-up potential. Each day, users have 24 hours to message their match, and then a week to set up a date before they vanish into the ethers. The point is to keep the conversation going, instead of just letting messages and matches accumulate while users see who else is out there.

While the design is game-like (you can get “coffee beans” by providing information or referring friends to the service, which in turn can be used to access additional features, like the ability to see who your mutual friends are, or to rekindle the flame with a match you neglected to message in time.) The company also teamed up in certain cities with local businesses to offer discounts to places you could go for a first date, although the growth of the app nation-wide has prevented them from doing this in more than a few major cities.

The additional funding will pay for engineers and developers to help build the core business so it can handle the projected growth in users. While the company hasn’t publicly shared their subscriber figures lately, the interest from investors is telling.

CMB has been compared to dating app Hinge and Are You Interested, which also focus on matches based on mutual social media connections.

The additional financing follows the company’s earlier participation in the TV series “Shark Tank,” where the founders proposed their business plans to celebrity investors in the hopes of gaining additional funding. While they didn’t get it from the TV show’s panel of judges, they have been successful in raising the funds elsewhere.
