What is the difference between a company's logo that has a small picture beside the company's name like that of stackexchange beside which there is a small logo of something like a message icon and a company's logo with just the name of the company without any image beside its name, like for example "SAMSUNG" where is it only the word "SAMSUNG" colored WHITE?
Obviously it is easier if I want to create logo to create the latter, just a name with a unique color, but I am not sure if there rules and regulations for what kind of logo to choose?
If I choose the second type of logo, should I draw the letters by hand or I can choose any font on Adobe for that?
