Barry O'Farrell, Premier of New South Wales, announced today that he will resign due to accepting an expensive bottle of wine as a gift and failing to tell yesterday's ICAC hearing about it.

I make no judgement on him, but it did make me wonder why companies give out gifts. Why invite even a whiff of corruption by doing that?

When a gift is a bribe...

I know several people who have received corporate gifts from companies trying to gain or maintain their business. These are relatively small things: tickets to a sporting match, a free dinner and drinks, movies tickets, etc. Those people all accepted the gifts, and apparently didn't consider them to be bribes. There seems to be a widespread acceptance that corporate gifts are a normal and legitimate promotional tool.

But surely most people would consider it to be bribery if a sales rep gives you $100 cash in a private meeting where he touts for business from your employer? So how is it different if a company gives you a $100 sporting ticket in a private email and calls it a 'corporate gift'? I don't see the distinction: for me, a corporate gift is a bribe.

There has been much scorn for the characters appearing at ICAC who gave away expensive corporate gifts; I'd like to see that same public scorn for all corporate gifts.

...and when legitimate promotion

I think the reason we're too accepting of corporate gifts is that people mix them up with legitimate promotion.

When a company promotes itself to you, the primary value you should get out of the promotion is that company selling you a great product or service which helps your business. If the primary value you get out the promotion is the cash value of a gift, then it's a bribe.

My view is:

• Giving away a free sample of your product to a potential client is legitimate promotion, whereas giving away someone else's product is a bribe
• Giving away an inexpensive branded item such as a pen is legitimate promotion, whereas giving away a desirable luxury pen is a bribe
• Giving away an expensive item as a prize in a competition is legitimate promotion, whereas giving away that prize directly to a person of your choosing is a bribe

One thing I hope Australians learn from today's events is: don't associate yourself with the kind of company that thinks it's OK to hand out corporate gifts.

It's hard to miss when a new series of Game of Thrones starts... the media and bloggers love to talk about it, and you'll probably hear a lot about it from your friends too.

What isn't so obvious is how to watch it in Australia. It took me quite some time to investigate all the options, so I've made this brief overview.

Game of Thrones Season 4

I found five ways to watch the Season 4 in Australia without pirating it. All prices are for the HD version — because if you're not watching HD you should re-evaluate your life choices:

* Estimated price

Foxtel iQHD: $580

This is the traditional way of watching Foxtel. They install a cable into your house and put a box next to your TV.

The minimum possible cost is $580, which comprises of:

• $150 installation
• $84 x 6 months for the 'Premium Movies & Drama' package
• minus a $74 'First Month Free' discount
  (yes, it doesn't quite cover the whole first month)

Foxtel iQHD is absurdly expensive. $580 would buy you excessive numbers of movies and TV shows from just about anywhere else, so it's not an option to take seriously.

Foxtel Play: $105

Kudos to Foxtel for introducing a more reasonably priced service with Foxtel Play. Foxtel is trying to increase its subscriber numbers by preventing iTunes from screening Season 4, which caused a lot of anger from Aussies who paid $34 to watch Game of Thrones on iTunes last year. I very much doubt that Game of Thrones would have gained extra subscribers for Foxtel if the only option was an iQHD subscription costing nearly twenty times more than iTunes.

Unlike Foxtel iQHD you're not locked in to a contract. However you need at least a three month subscription because Game of Thones Season 4 runs for ten weeks. So the minimum possible cost is $105, which comprises of:

• $50 per month for 3 months
• minus $15 per month discount up to 3 months

If you absolutely must watch Season 4 now, it seems Foxtel Play is the best option. But at three times the price of last season it's still far too expensive. You're paying a very large tax for being impatient!

Another disadvantage is that you can't watch the show again after you end your subscription. Do you want to watch Season 4 again just before the next year's Season 5 so you remember what was going on? That will cost you another $50.

But the best reason to now choose the Foxtel Play option is that it will only encourage Foxtel to do it again. Their deal over Game of Thrones took away the great option I had last year, leaving me with their inferior Foxtel Play. I don't want this to be a success for them, because if it is then we might see more shows locked up and taken away from sale.

For that reason alone I'm not choosing Foxtel Play.

iTunes and Quickflix: $34?

Exactly when Game of Thrones will appear on iTunes and Quickflix is a mystery. Last year they both had Season 3 within hours of the first US broadcast, and they both charged $34 for the entire season. That's a one off purchase price, not a subscription fee, so you can watch them again any time you like.

This year Season 4 is not available on iTunes or Quickflix yet, but it seems likely that all the episodes will arrive at once in mid June.

We know that iTunes and Quickflix can't screen Season 4 until after Foxtel finishes their screenings, and by my reckoning the last episode of Season 4 will screen on 16 June on Foxtel (ie shortly after the US release).

Does that mean iTunes and Quickflix will release the show 16 June 2014? We can't know the date for sure, but I'm sure they won't waste a minute getting it out there as soon as they're permitted. The Quickflix executive chairman Stephen Langsford expects Quickflix to have Season 4 around June.

Blu-ray: $50?

Last season's DVD and Blu-ray discs were released in Australia on 19 February 2014, nearly a year after Season 3 was first shown on TV. Prices generally seemed to be in the $50-60 range.

Release dates for the Season 4 Blu-ray have not been announced, but there's no reason to think it would be any faster this time. Expect to wait until February 2015 if you want a Blu-ray disc.

The best option

For me the choice is clear: iTunes.

It's cheap, it's legal, I don't have to wait long until it arrives, I can keep it forever and I can watch it as often as I like. I prefer iTunes over Quickflix because I have an Apple TV, but Quickflix and iTunes are equally as good.

With the money I'm saving by not subscribing to Foxtel, I'm buying all three seasons of the excellent ABC comedy Rake on iTunes... a much better investment!
