There are actually two questions here:
1. Can I study History at university without having studied it at A level?
2. Can I study History at university having done "media" college?
The answer to the first question is a definite "Yes". Pick some universities at random, visit their web site, and check their entry requirements. Some will specify a requirement for previous study in History; some will not. (For an example if one that doesn't, see University if East Anglia,
here).
The answer to the second question depends on what you mean by "I did media". Is this a BTEC? What is the
full title of the course? For example, "Pearson BTEC Level 3 National Extended Certificate in Creative Digital Media Production" or "Pearson BTEC Level 3 National Extended Diploma in Creative Media Practice".
The full title of the course is important, but what's particularly important is the bit which says "Diploma", "Extended Certificate", or whatever.
