[Jurassic Park] What is Ingen? What do they do for the park? Why is it a bad thing when they appear?
gpt
Ingen, also known as International Genetics Inc., was the bioengineering company started by John Hammond to create the first dinosaurs for Jurassic Park. After that initial success, the company began to diversify, in a sense, and their focus turned to the general "resurrection" of extinct species. After the failure of Jurassic Park, Hammond was removed as CEO and the company severely floundered for a bit until being put under the direction of Hammond's nephew, Peter Ludlow. 

This is where some of the more "nefarious" aspects of InGen began to surface, as Peter looked to find more "profitable" avenues for the type of bioengineering that they were doing. Large corporations and the military had strong interests in the research they were doing, and the overall focus of InGen began to drastically shift as powerful, moneyed interests started to guide their path. 

When Simon Masrani became CEO, that's when Jurassic World went from an idea to a reality. While Masrani's overall focus was on the park, in the background there was a lot more happening (i.e. that military guy saying "Masrani's so diversified he doesn't even know what he owns", and Masrani being surprised by the actions of InGen's head of research). 

**Tl;dr** = So, in summary, InGen was the brainchild of Hammond and the means by which Jurassic Park came to be. When the park failed, the company began to heavily diversify under new management to save itself. This diversification lead to a major corruption of Hammond's initial vision. It's a "bad thing" when InGen officials start showing up, because we learn that this research is being used to further military and corporate interests behind the back of the company's CEO.
