Back then is was more philosophical than existential - we debated whether it was morally acceptable for a writer to take into consideration the size of a company's ad account when covering them in a story; now that the focused channel of broadcast media has been fragmented, so advertisers no longer pay a premium for access to readers and viewers of the nightly news, every journalist has to be mindful of their commercial impact (though this still needn't impact their writing choices) because they may be out of a job next week.
Plus ça change and all that. I'd like to see more debates around how to fund the new model (now that we've discovered it was the channel, not the content, that people actually valued for a couple of hundred years), not all this hand-wringing about the impact of money on objectivity because that's an old, boring conversation. Ultimately, advertising has been funding journalism for a long, long time. I wish it wasn't so, but I also wish it rained doughnuts.
