Rejected by Facebook Jan Koum is of Jewish descent, born in 1976 into a poor family on the outskirts of Kiev, the capital of Ukraine. Koum’s father worked as a hospital and school construction manager, and his mother worked as a housewife. At the age of 16, Koum followed his mother and grandmother to the US to settle first, intending to settle down to welcome his father. They live off social welfare, from food stamps for those who cannot afford food. Koum’s mother takes care of the kids to earn extra money, while Koum cleans a grocery store. Koum still uses notebooks and pens brought from Ukraine because he lacks money to buy them. In 1997, when Koum was 21 years old, his father died in his hometown. Three years later, Koum’s mother also died in the US from cancer. In high school, Jan Koum didn’t have many friends and was seen as an outcast. He almost failed to graduate because of his lack of education. Jan Koum finds joy in his old computer. This time, Koum joins a hacker group called woowoo. With the experience gained from this hacker group, he applied for the exam and entered the University of San Jose. During his studies, he worked for Ernst and Young Auditing Company in the position of security vulnerability tester. In 1997, he ran into Yahoo employee Brian Acton. With the help of Acton, Koum got a job in cybersecurity six months later at Yahoo. Koum decided to leave school to focus on working for Yahoo. After 9 years at Yahoo, Koum rose to the position of infrastructure manager. In 2007, Koum and Acton both quit their jobs at Yahoo, spending time traveling South America in search of new inspirations. When they returned, the two applied to Facebook together, but were rejected. During his unemployment, Koum mulled over his next job. Buying an iPhone, Koum realized he could succeed with apps from the App Store. Koum came up with the idea to let people set up status updates on their phones. He said: “I am annoyed because I miss a lot of calls when I am at the gym. So I came up with the idea of ​​an app that lets friends know if the person on the other end of the line is ready to take a call, with a feature called “status”. We didn’t originally plan to start a company, we just wanted to make a product that people could use.” In February 2009, Koum and Acton co-founded WhatsApp, turning the product into a messaging app. At first, the cost to verify SMS for users cost about 500,000 USD/month, making Koum’s bank account almost exhausted. By December 2009, they updated a new version for WhatsApp on iPhone, making it possible for this application to send images, immediately the number of users increased. To ensure coverage, WhatsApp charged about $1 a month to use, which brought in about $5,000 in revenue in early 2010, enough to cover expenses later. By February 2013, when the number of WhatsApp users reached about 200 million and the number of employees was 50, Acton and Koum decided to organize a fundraiser and was invested 50 million USD by Sequoia Investment Fund, increasing the value of WhatsApp to 1 , 5 billion USD. The founding duo is very concerned about security for users. “We want to know as little of the user’s information as possible. We don’t run ads, so we don’t need personal data,” Koum said. WhatsApp quickly grew without any marketing or PR campaigns, especially in less developed countries where users rely heavily on SMS messages. Return to conquer the big man WhatsApp’s growth caught the attention of Facebook’s CEO. In 2012, Mark Zuckerberg phoned Koum to express his interest in WhatsApp. The two then kept in touch, often climbing mountains and chatting about the topic of world connection. In February 2014, Zuckerberg met Koum and offered to buy WhatsApp for $19 billion (including $4 billion in cash, the rest in Facebook stock). At the time Facebook acquired WhatsApp, the app had 450 million monthly active users. In 2019, this number has reached 1.5 billion. By February 2021, the application has surpassed 2 billion users in 180 countries, is the world’s most popular free messaging application over the internet today. However, the sale of WhatsApp by co-founders Jan Koum and Brian Acton is said to be a bad decision. The biggest split between WhatsApp and Facebook is the messaging app’s monetization policy. Koum and Acton have resisted the adoption of Facebook’s widespread advertising model, which uses personal data to allow marketers to show ads to specific sets of customers on the social network. Those disagreements have led to tensions with Facebook CEO Mark Zuckerberg and COO Sheryl Sandberg. Acton left WhatsApp in 2017, 8 months later Jan Koum also left. “I sold my company. For great personal gain I sold my users’ privacy to Facebook. I made a decision and compromised with that and I regret it” – Jan Koum shared with Forbes. After the two founders left, Facebook persisted with the policy given to WhatsApp. In early January 2021, WhatsApp made a controversial decision, when it changed its policy and terms of use, requiring WhatsApp users to agree to the sharing of their personal information with the parent company Facebook. and Facebook affiliated companies. According to WhatsApp, sharing information will help this application better understand users, in order to improve and enhance the quality of the service. However, this move of WhatsApp has angered many users and called for a boycott of the application, because they do not want to share their information with Facebook. Many WhatsApp users have switched to other free internet messaging apps and services, like Telegram and Signal. In 2014, Jan Koum entered Forbes’ list of the 400 richest Americans at number 62, with an estimated net worth of $7.5 billion. As of August 2020, his net worth is estimated at $10 billion.

The relationship between Prince Philip and Queen Elizabeth II began when they were young and the queen was still a princess. At the age of 13, while following her family to visit the Royal Naval Academy Britannica, Princess Elizabeth that day immediately fell in love with Greek Prince Philip, who was training officers there. In the years that followed and during World War II, they corresponded. Not long after the war ended, Prince Philip proposed to Princess Elizabeth in Scotland. The engagement ring was made by Philip Antrobus, a London jeweler, crafted from diamonds on the prince’s mother’s crown. However, the engagement was kept private until the princess turned 21 at the request of King George VI, the princess’s father, who ruled England at that time. In addition, in order to marry Princess Elizabeth, Prince Philip had to give up his title of Greek Prince in order to become a British citizen. After much trouble, the wedding was scheduled on November 20, 1947 and took place at Westminster Abbey. Instead of holding a grand event, King George VI ordered a wedding as compact as possible so as not to offend the people by the new country that has gone through the war. The princess’s wedding dress was designed by Norman Hartnell, made from ivory silk, satin duchesse and silver thread, with crystal and 10,000 pearl beads, with a veil longer than 4.5 meters. The dress is completed in 7 weeks by 350 skilled tailors. Like many brides at the time, Princess Elizabeth had to save on stamps in order to buy materials for her wedding dress design. The British government has sent an additional 200 stamps to help her. Princess Elizabeth’s wedding day crown is named Queen Mary Fringe Tiara. It was originally a wedding gift in 1893 of Queen Mary, the princess. In addition, the bride is adorned with 2 pearl bracelets, one of which is said to belong to Queen Anne. Princess Elizabeth’s wedding bouquet is similar to every British royal bride’s wedding bouquet – they contain myrtle flowers from the myrtle bushes planted by Queen Victoria. This flower also appears on the seats in the reception reception at Buckingham Palace, next to the bouquet of white and pink carnations on the banquet table. Because this is the wedding of the future queen, the wedding is reported directly to millions of people via radio. Nearly 2,000 guests attended this historic wedding, including the King of Iraq, Princess Juliana and Prince Bernhard of the Netherlands, Grand Duke of Luxembourg and Princess Elisabeth of Luxembourg. Two wedding rings are made from a block of gold in the Clogau St David mine. According to British royal biographer Ingrid Seward, Duke Philip engraved a secret message into the ring given to his wife that only the person who engraved them, he and Princess Elizabeth, knew the contents. After the ceremony was over, a reception was held at Buckingham Palace and was open to only 150 guests. Dishes served include Filet de Sole Mountbatten, Perdreau en Casserole and Bombe Glaceé Princess Elizabeth. Here, the couple cut wedding cake decorated elaborately weighing 227 kg, 2.7 m high with the groom’s sword. More than 10,000 people telegrams to celebrate the marriage of Princess Elizabeth and Duke Philip. 2,500 wedding gifts were sent from all over the world, including the cloth woven by Mahatma Gandhi himself. After the reception, the couple went to Waterloo Station with their corgi dog Susan to catch the train to Hampshire. They spent the wedding night in Broadlands, the hometown of Philip. The rest of the royal honeymoon takes place in Birkhall (Scotland).
