Party election broadcasts, as distinct from political advertising, are usually described as "free". But all this means is that the parties themselves do not pay for the time that is allocated to them. This leaves unanswered two questions:
In practice there are two possible answers to the first question: either the broadcaster is required to provide the time for free, or the government or electoral authority will purchase the time from the broadcasting company. For public broadcasters, the answers will almost always be the first. The charter or regulations governing the public broadcaster will require them to provide this service. In some cases a similar public service obligation might exist for private broadcasting licensees. But in the latter case it is more common that a supervisory body will buy the time on the parties' behalf. This is what happens in Mexico, for example, where the Federal Electoral Institute buys and allocates 15 minutes a month of television and radio time for each party.
In some exceptional circumstances, a third party pays. In Afghanistan for the 2004 and 2005 elections, direct access production and airtime was arranged, managed and paid-for by donors.
The second question - who pays for the programme content itself - is altogether more complex. Usually, the answer is the party, although this in itself may be constrained by legal limits on campaign spending. Costs can be kept relatively low by the use of sympathetic personnel - most famously the Hollywood film directors John Schlesinger, Hugh Hudson and Mike Newell, who have made party election broadcasts for the main parties in Britain (although in each case the saving on the director's fee was probably more than offset by the high production costs).
If the party makes its own election broadcasts, this clearly favours the richer parties.
An alternative solution is for the public broadcaster to put production facilities at the parties' disposal. This was the approach in the early days of party political broadcasts, which were studio-bound and really just an extension of the old-fashioned ministerial address to camera. It has been revived in transitional democracies where new parties are unlikely to have either the funds or expertise to produce their own broadcasts.
