The quality and content are constantly increasing their relevance in the conditions of modern education. If quality can be understood as means and educational materials which are used in the process, the content is a sign of the diversity of these materials and a factor which takes into account the age, abilities and chances of learners. Taking into account these two important factors, the theoretical and practical bases of combining modern information technologies in improving the quality and content of the system of blended learning at philological higher education institutions of specialized in teaching English are described in detail. In addition, the paths and stages of creating a specific system that runs continuously, combining the effective and reasonable functions of social networking services (SNS) and messengers in consolidating the quality and content indicators of blended learning, are gradually illustrated. Besides that, by combining online educational materials with traditional place-based classroom methods at philological higher education institutions which are specialized in teaching English based on the approach of blended learning, the system of fostering students’ linguistic skills, such as reading, writing, listening, and speaking can be optimized and modernized according to the results of this research in the article.
