Colombian Corporations

I was reading a couple of biographies of Colombian tycoons such as Carlos Ardida Lulle and Julio Mario de Santo Domingo. Both have common traces: they started with drinking products and they ended up at the media business. The former got rich with Postobon, a drinks company and then bought RCN Television, together with many other companies from textile, building an so on. Santo Domingo, on the other hand, started with Cervecería Aguila, which purchased Cervecería Bavaria and became Cervecería Bavaria S.A., the biggest beer company in Colombia and, after buying 15, 1% of SAB Miller, becoming the second major shareholder of the second biggest beer company in the world. Santo Doming owns Caracol Television, the second private channel in Colombia.
What is this all about? Well, there are four big companies in the country: Organización Ardida Lulle, Grupo Bavaria, AVAL (building company owned by Luis Carlos Sarmiento) and the Sindicato Antioqueño. The two first ones are polarized by these two tycoons with interests in both beer and media, I think it is difficult to compete with a structure where your product can be widely advertised in your media. But also this happens in a country where some other industries (the high-level added value ones) are not developped.
Hence, which sectors could be interesting to invest in Colombia?
