Charismatic species are visually and emotionally appealing animal species commonly used by conservation groups to increase public support for conservation and raise funds. Keystone species are those that have a significant effect on their ecosystem, such as mangrove trees, starfish, prairie dogs. Some charismatic species, such as African elephants, African lions, and sea otters, are also keystone species, while others, such as giant pandas, giraffes, and koalas, are not generally considered keystones.

Some video game publishers have abandoned a fixed pricing model for video games (where you purchase a video game at a set price) for a 'free to play' model. Free-to-play means the base game can be downloaded and played without charge. Revenue is generated through optional in-game purchases, which may include cosmetic items, additional content, convenience features or gameplay advantages, depending on the game. Examples of games that use the 'free to play' model include Fortnite, League of Legends, and Roblox. Games with a set price upfront include Skyrim, Animal Crossing, and Call of Duty. 

In the UK model of post-secondary program admissions, students are admitted directly into their chosen program/major, which in some cases can include direct entry into medicine, law, or other professional programs. In the Canadian model, students are often admittied only into a general area of study, and declare a major later. Medicine, law, and other professional programs must be applied to separately, often after students have completed an undergraduate degree.
