<p>Ah, u<em>u</em>d, I am going to guess that you live in California, where many companies are in the business of writing software and selling it. In that case, where the main product of the company is to produce a software product to sell, then you would have a “software development” division, separate from the internal systems & applications area (what I think you are calling IT). And, of course, there are many, many jobs for computer science majors in those companies. But there are also hundreds of thousands of jobs for companies that do not have software development as their primary business focus, and those companies typically have only one technology division as I described above. I think this is a difference in geography 
Of course, there are software development companies outside CA, but a much smaller percentage of the computer related jobs (okay, except in Redmond…) are for actual sofware companies.</p>
<p>So, OP, both perspectives are correct, but it depends on which type of company you are looking at. Just an FYI, Fortune 500 companies that are not in the software business often have very large technology departments (I have worked with companies that have several thousand in some computer-intensive industries like financial services).</p>
<p>I don’t know how the job market splits percentage-wise on this (% of computer science type jobs in software companies vs. non-software related industries). It would be interesting to know for someone who was job hunting in the field.</p>
<p>OP, regarding your question on how to apply, that is a perfect question to take to admissions at each college. But here is another tip… I did not actually MINOR in Computer Science, as my college did not allow it (University of Michigan, and my degree is from the Ross School of Business within U of M). What they did allow was for me to take classes in other schools at the University (Computer Science was in Literature, Science, and Arts at that time). In fact, at Michigan all undergrad business majors spend two years in some other school, then start business courses in their Junior year. So there are two years when you can take a lot of other stuff, and get in some computer science courses then. I was also able to take about 1 course a semester the last couple of years (jr. & sr. year) that were not in the School of Business. So I took lots of computer classes, and just listed in the education section of my resume, “Bachelor of Business Administration, Marketing Major. Also took X computer science courses.” And then in my cover letter for job applications, I just said that I was interested in both areas. Worked for me… But if you ask the various colleges, you may be able to find a way to have a formal minor in c/s (or business if you want to major in c/s and minor in business).</p>
