WebbShannon's theory doesn't concern itself with what news, message or information is communicated from s (source) to r (receiver) or, indeed, whether anything intelligible is … WebbShannon entropy is the creation of Shannon (1948) based on the experiences in Bell System Company during and after the Second World War. Then, Renyi (1961) generalized it for one parameter families of entropies. This entropy for discrete random variables is non-negative but it can be negative in continuous case.
