NBC Politics Bot allowed users to engage with the conversational agent via Facebook to identify breaking news topics that would be of interest to the network’s various audience demographics. After beginning the initial interaction, the bot provided users with customized news results (prioritizing video content, a move that undoubtedly made Facebook happy) based on their preferences.
The issue is only going to get more relevant. Facebook has made a big push with chatbots in its Messenger chat app. The company wants 1.2 billion people on the app to use it for everything from food delivery to shopping. Facebook also wants it to be a customer service utopia, in which people text with bots instead of calling up companies on the phone.
Bots are also used to buy up good seats for concerts, particularly by ticket brokers who resell the tickets. Bots are employed against entertainment event-ticketing sites. The bots are used by ticket brokers to unfairly obtain the best seats for themselves while depriving the general public of also having a chance to obtain the good seats. The bot runs through the purchase process and obtains better seats by pulling as many seats back as it can.
Companies use internet bots to increase online engagement and streamline communication. Companies often use bots to cut down on cost, instead of employing people to communicate with consumers, companies have developed new ways to be efficient. These chatbots are used to answer customers' questions. For example, Domino's has developed a chatbot that can take orders via Facebook Messenger. Chatbots allow companies to allocate their employees' time to more important things.
“We believe that you don’t need to know how to program to build a bot, that’s what inspired us at Chatfuel a year ago when we started bot builder. We noticed bots becoming hyper-local, i.e. a bot for a soccer team to keep in touch with fans or a small art community bot. Bots are efficient and when you let anyone create them easily magic happens.” — Dmitrii Dumik, Founder of Chatfuel
Fast food just got faster. With Burger King’s new bot, simply order and pick up on demand. Simply choose menu items and pick the closest restaurant to pick it up. The bot then provides an estimated time and price. The bot is not available yet, but you can see from the demo, how it will work. It probably won’t tell you the calorie counts per menu item, but you can bet this bot will be programmed to inflate food sales.
Malicious chatbots are frequently used to fill chat rooms with spam and advertisements, by mimicking human behavior and conversations or to entice people into revealing personal information, such as bank account numbers. They are commonly found on Yahoo! Messenger, Windows Live Messenger, AOL Instant Messenger and other instant messaging protocols. There has also been a published report of a chatbot used in a fake personal ad on a dating service's website.
Since 2016 when Facebook allows businesses to deliver automated customer support, e-commerce guidance, content and interactive experiences through chatbots, a large variety of chatbots for Facebook Messenger platform were developed. In 2016, Russia-based Tochka Bank launched the world's first Facebook bot for a range of financial services, in particularly including a possibility of making payments.  In July 2016, Barclays Africa also launched a Facebook chatbot, making it the first bank to do so in Africa. 
Simple chatbots work based on pre-written keywords that they understand. Each of these commands must be written by the developer separately using regular expressions or other forms of string analysis. If the user has asked a question without using a single keyword, the robot can not understand it and, as a rule, responds with messages like “sorry, I did not understand”.
There are two types of chatbots available: those that function based on rules and those that use artificial intelligence (A.I.). Chatbots that function based on rules are much more limited than those that work with A.I. because they only respond to specific commands. Hence, they require a great deal of programming in order to be an effective tool. Chatbots tools that are powered by artificial intelligence are more dynamic because they respond to language, and don’t require specific commands. They learn continuously from the conversations they have with people and can help fulfill an array of tasks without a monumental amount of programming.
Chatbots talk in almost every major language. Their language (Natural Language Processing, NLP) skills vary from extremely poor to very clever intelligent, helpful and funny. The same counts for their graphic design, sometimes it feels like a cartoonish character drawn by a child, and on the other hand there are photo-realistic 3D animated characters available, which are hard to distinguish from humans. And they are all referred to as ‘chatbots’. If you have a look at our chatbot gallery, you will immediately notice the difference.
