Welcome to purgatory, Fool. Your dividends are no longer good here.

Research from Standard & Poor's shows that 288 of the roughly 7,000 public companies that report dividend information decreased their payouts during the last three months of 2008. It was the worst quarter for dividends since S&P began collecting such data back in 1956.

Notable 2008 cutters included General Motors (NYSE:GM), Regions Financial (NYSE:RF) and LCA-Vision (NASDAQ:LCAV). For the year, Capital IQ found 485 dividend reductions by companies and closed-end funds.

At least there's Prozac
If this sounds like a huge problem, it is. According to research from Wharton professor Jeremy Siegel, during the 132 years between 1871 and 2003, 97% of returns came from dividends on the original investment.

Big gains in 2003, 2004, and 2006 may have altered the equation some since, but for the most part, dependable dividends continue to help produce returns, especially among blue chips. The large-cap-weighted S&P 500 index yields more than 3% as of this writing.

But we don't know whether that yield, or any yield, is sustainable. The Great Dividend Implosion of 2008 has raised doubts. Thanks, Washington Mutual. You, too, Wachovia.

Is there any hope? Not really, said S&P analyst Howard Silverblatt in a recent interview with the Indianapolis Star:

Companies are not willing to commit to increases, but they don't want to have to cut their dividends because that's a poor sign. There's a lot of moving parts here ... Dividends are very insecure.

And the audience replied, "How insecure are they?"
Silverblatt is probably being cautious; as an analyst, he's paid to be. In truth, 2008 wasn't as bad a year for dividends as the headlines suggest.

In fact, it wasn't even close. Capital IQ spotted 1,744 dividend increases last year -- firms were 3.6 times more likely to raise their payout than lower it. History favors increases even more:
