It's not a fair comparison. Writing for TV and writing novels are two wildly different beasts. As a novelist you have final say over every element of your work. If you want to misspell every word, no one will stop you. In TV, there's no author. It's an endless team of people. At least 6 writers, usually closer to 10. Not to mention studio executives, network executives, actors, directors, production ... each with their own take, each with their own say. And as the writer, even as the show runner, you never have final say. Someone -- whether it be on the network side or studio side or even S&P, out ranks you.
