Smart tablet users reached a total of 1 billion in 2015, 15% of the world's population. The statistics evidence the impact of digital media communications today. What is also of relevance is the fact that the numbers of smart device users is rising rapidly yet the amount of functional uses increase daily. A smartphone or tablet can be used for hundreds of daily needs. There are currently over 1 million apps on the Apple Appstore. These are all opportunities for digital marketing efforts. A smartphone user is impacted with digital advertising every second they open their Apple or Android device. This further evidences the digital revolution and the impact of revolution. This has resulted in a total of 13 billion dollars being paid out to the various app developers over the years. This growth has fueled the development of millions of software applications. Most of these apps are able to generate income via in app advertising. Gross revenue for 2020 is projected to be about $189 million. Compared with print media, the mass media, and other analog technologies, digital media are easy to copy, store, share and modify. This quality of digital media has led to significant changes in many industries, especially journalism, publishing, education, entertainment, and the music business. The overall effect of these changes is so far-reaching that it is difficult to quantify. For example, in movie-making, the transition from analog film cameras to digital cameras is nearly complete. The transition has economic benefits to Hollywood, making distribution easier and making it possible to add high-quality digital effects to films. At the same time, it has affected the analog special effects, stunt, and animation industries in Hollywood. It has imposed painful costs on small movie theaters, some of which did not or will not survive the transition to digital. The effect of digital media on other media industries is similarly sweeping and complex. Between 2000–2015, the print newspaper advertising revenue has fallen from $60 billion to a nearly $20 billion. Even one of the most popular days for papers, Sunday, has seen a 9% circulation decrease the lowest since 1945. In journalism, digital media and citizen journalism have led to the loss of thousands of jobs in print media and the bankruptcy of many major newspapers. But the rise of digital journalism has also created thousands of new jobs and specializations. E-books and self-publishing are changing the book industry, and digital textbooks and other media-inclusive curricula are changing primary and secondary education. In academia, digital media has led to a new form of scholarship, also called digital scholarship, making open access and open science possible thanks to the low cost of distribution.
