As per wikipedia.org Plepler moved to the New York City in 1984 and started a public relation firm, where he deliberated upon The Atlantic Magazine with his colleagues and clients and also shaped a documentary on the Israel and Palestine conflict. In 1992, Richard Plepler joined Times Warner, and in these nearly three decades, he proved his mettle in this arena. Several of the HBO’s significant projects- Game of Thrones, Veep and others bloomed under his guidance. Plepler thus contributed significantly in the development and improvement of HBO Go and HBO Now.
Richard Plepler, the Co-President of HBO from 2007 and then the Chairman and the CEO of HBO from 2013, has been made to step down from his chair. It was announced on February 28, 2019, that Plepler is all set to leave HBO, arising out of the process of restructuring in the parent company AT&T.
Last year, according to gizmodo.com AT&T’s controversial merger with WarnerMedia was sealed as the Department of Justice was unsuccessful in providing evidence in legitimizing the deal. Richard Plepler’s exclusion also comes in conformity to WarnerMedia’s CEO John Stankey plans to plug in Bob Greenblatt, the former NBC Entertainment Chairman and launch a new streaming service. This new one is a joined venture of HBO and CNN. Many feel that Pepler’s exit is a loss to AT&T and that now the brand will survive without its soul.
Plepler had a philosophical realization regarding his exclusion as he felt; it is the right time for him to get relief. According to him, his professional era was “a journey of great pride and accomplishment because so many of you, and many others before us, have made HBO a cultural and business phenomenon.“
