There's so many shorts on the internet, people won't just stumble across yours. TV stations that have a regular short film program are also rare, and they even rarer consider submissions.
The most "reliable" way to get some attention is to win some awards at festivals, at leadt they watch the submissions sent to them, so there's a chance of getting shown there. That's a first step towards getting it shown on tv.
