Dilemma in choosing organization

I initially decided to go for publishing industry and found a principal company to work on , I did my initial research on that company and realized more of its success is due to acquisition strategy / model. But I am unable to find a suitable a competitor. Due to this I am deciding to work on airline industry now. I have to do r&d from scratch. Is it advisable to change the industry ? And I am targeting for UK based organizations.
