The current era of logo design began in the 1950s. Today there are many corporations, products, brands, services, agencies and other entities using an ideogram (sign, icon) or an emblem (symbol) or a combination of sign and emblem as a logo. As a result, only a few of the thousands of ideograms people see are recognized without a name. It is sensible to use an ideogram as a logo, even with the name, if people will not duly identify it. Currently, the usage of both images (ideograms) and the company name (logotype) to emphasize the name instead of the supporting graphic portion and making it unique, by it non-formulaic construction via the desiginal use of its letters, colors and any additional graphic elements.
Designing a good logo is not a simple task and requires a lot of involvement from the marketing team and the design agency (if outsourced). It requires clear idea about the concept and values of the brand as well as understanding of the consumer or target group as marketers call. Broad step in logo design process would be formulating concept, doing initial sketch, finalizing the logo concept, deciding the theme colours and format.
