The acceptance of dating systems, however, has created something of a resurgence in the role of the traditional professional matchmaker. Those who find dating systems or services useful but prefer human intelligence and personal touches can choose from a wide range of such services now available. According to Eddie Hernandez (a dating coach), With television shows like “Million Dollar Matchmaker” and “Indian Matchmaking,” and a pandemic that has made it harder for singles to meet organically, matchmaking is hot again. “There used to be this stigma around it,”. 
In some cultures, the role of the matchmaker was and is quite professionalised. The Ashkenazi Jewish shadchan, or the Hindu astrologer, were often thought to be essential advisors and also helped in finding right spouses as they had links and a relation of good faith with the families. In cultures where arranged marriages were the rule, the astrologer often claimed that the stars sanctified matches that both parents approved of, making it quite difficult for the possibly-hesitant children to easily object – and also making it easy for the astrologer to collect his fee.[ citation needed ] Tarot divination has also been employed by some matchmakers.[ citation needed ]
Social dance, especially in frontier North America, the contra dance and square dance, has also been employed in matchmaking, usually informally. However, when farming families were widely separated and kept all children on the farm working, marriage-age children could often only meet in church or in such mandated social events. Matchmakers, acting as formal chaperones or as self-employed 'busybodies' serving less clear social purposes, would attend such events and advise families of any burgeoning romances before they went too far.[ tone? ][ citation needed ]
The influence of such people in a culture that did not arrange marriages, and in which economic relationships (e.g. "being able to support a family", "good prospects") played a larger role in determining if a (male) suitor was acceptable, is difficult to determine. It may be fair to say only that they were able to speed up, or slow down, relationships that were already forming. In this sense they were probably not distinguishable from relatives, rivals, or others with an interest. Clergy probably played a key role in most Western cultures, as they continue to do in modern ones, especially where they are the most trusted mediators in the society. Matchmaking was certainly one of the peripheral functions of the village priest in Medieval Catholic society, as well as a duty of rabbis in traditional Jewish communities. Today, the shidduch is a system of matchmaking in which Jewish singles are introduced to one another in Orthodox Jewish communities.[ citation needed ]
In Singapore, the Social Development Unit (SDU), run by the city-state's government, offers a combination of professional counsel and dating system technology, like many commercial dating services. Thus the role of the matchmaker has become institutionalized, as a bureaucrat, and every citizen in Singapore has access to some subset of the matchmaking services that were once reserved for royalty or upper classes.[ citation needed ]
The concept of matchmaking is also used in the business world and is known as B2B Matchmaking, Investor Matchmaking, Business Speed Dating, or Brokerage Events. In contradiction to social networking solutions, real meetings between business people are in focus. Trade fair organisations e.g. find this concept an added value for their exhibitors because it gives them the opportunity of advanced planned meetings. Following the inspiration of dating sites, some online B2B networking platforms developed advanced business matching solutions enabling relevant business partners' identification.
An internet relationship is a relationship between people who have met online, and in many cases know each other only via the Internet. Online relationships are similar in many ways to pen pal relationships. This relationship can be romantic, platonic, or even based on business affairs.

The major difference here is that an internet relationship is sustained via computer or online service, and the individuals in the relationship may or may not ever meet each other in person. Otherwise, the term is quite broad and can include relationships based upon text, video, audio, or even virtual character. This relationship can be between people in different regions, different countries, different sides of the world, or even people who reside in the same area but do not communicate in person.

Anonymous matching is a matchmaking method facilitated by computer databases, in which each user confidentially selects people they are interested in dating and the computer identifies and reports matches to pairs of users who share a mutual attraction. Protocols for anonymous matchmaking date back to the 1980s, and one of the earliest papers on the topic is by Baldwin and Gramlich, published in 1985. From a technical perspective, the problem and solution are trivial and likely predate even this paper. The problem becomes interesting and requires more sophisticated cryptography when the matchmaker isn't trusted.

Vietnamese migrant brides in Taiwan represent marriages between Taiwanese men and Vietnamese brides who are mostly from poor, rural areas of Vietnam, such as those along the Mekong Delta. As of 2006, out of Taiwan’s immigrant population of approximately 428,240 people, 18% were females who had relocated to the country through marriage. Out of this population, about 85% originated from the Southeast Asian countries of Vietnam, Indonesia, Thailand, and Philippines, with the majority hailing from Vietnam. It is estimated that between the years of 1995 and 2003, the number of Vietnamese women married to Taiwanese men increased from 1,476 to more than 60,000 individuals, making the Vietnamese the largest non-Chinese immigrant group living in the island. This event has been seen locally and abroad as something that can potentially evolve into a concerning societal and humanitarian issue. This issue is not just localised in Taiwan but also in Southern China provinces as well as Hong Kong and Macau. In every case, these practices are illegal and are classified under human trafficking.
